General comments The calibration_support collection has cruise data and will eventually have preflight calibration data. These products were used to classify and calibrate the Mastcam-Z instruments. The cruise browse products can be found under browse in calibration_support. The Mastcam-Z Derived Product SIS has been updated for this release. Sol 177 zstack merge zcam00040 has been RAD and IOF calibrated for this release. Sol 208 has thumbnail products (instead of the full resolution image), where the originally commanded image products were deleted from the camera DEA (memory) prior to downlinking. 2. Recovered products There are several sols with products which were recovered from the rover at different encoding (JPEG 50 vs uncompressed) or were recovered tactically. Recovered products were downlinked for imaging and video sequences and are distinguishable through the label (Ex. a recovered right image will have MczRRecoveredProduct in the label where the image has MczRImage). Sols Sequences ----- --------- 0240 zcam08263 0240 zcam08264 3. Cloned products There are several sols with products which were cloned from the rover at different encoding (ex. JPEG 50 vs uncompressed) or were recovered tactically. Cloned products were downlinked for imaging and video sequences and are virtually indistinguishable through the label (Ex. a cloned right image will have MczRImage in the label where the original (non-cloned) image also has MczRImage). Sols Sequences ---- --------- 0255 zcam08278 0265 zcam08281 0286 zcam01008 0289 zcam01000 0290 zcam01000 0292 zcam01000 0294 zcam01000 0296 zcam01000 0297 zcam01012 0298 zcam01005 0300 zcam01012 0310 zcam01010 0344 zcam08371 0395 zcam08418 For every cloned product there is a corresponding identical non-cloned product (full resolution image). 4. Known label keyword issues Known label keyword issues are present for all sols in this release. The following ODL3 label keywords can report incorrect values when sequences are built using the first image to set up the commanding and indicate no change for the images that follow. ODL3 Keyword Description ------------------------------ --------------------------------- INSTRUMENT_ZOOM_POSITION_COUNT This can incorrectly report as "0" when commanded in a group of images where all products are using the same zoom position. The actual zoom position count value can be found in the ZOOM_POSITION_COUNT keyword or by looking in the label of the first image acquired in the sequence. COMMANDED_FOCAL_LENGTH This can incorrectly report as "26.0 " when commanded in a group of images where all products are using the same focal length. The actual focal length value can be found in the FOCAL_LENGTH keyword or by looking in the label of the first image acquired in the sequence. INSTRUMENT_FOCUS_MODE This keyword is unreliable. To determine if an image was commanded using manual or autofocus you should look to the INSTRUMENT_FOCUS_STEPS and INSTRUMENT_FOCUS_STEP_SIZE keywords. If “INSTRUMENT_FOCUS_STEPS = 1” and “INSTRUMENT_FOCUS_STEP_SIZE = 6” The image was commanded using manual focus, if “INSTRUMENT_FOCUS_STEPS = 0” and “INSTRUMENT_FOCUS_STEP_SIZE = 0” there is no change from the previous image in a sequence and you should look to the first image acquired in the sequence, otherwise it was commanded using autofocus. Four keywords in the ODL3 label and are not present in the PDS4 XML label. NONLINEAR_PIXEL_THRESH NONLINEAR_THRESH SATURATED_PIXEL_THRESH SATURATED_THRESH 5. Unexpected scene and image content Some images did not contain their intended target or the target was unobservable. The issues reported below are from error tracking during tactical shifts. sol Sequence Description ----- --------- ------------------------------------------------------------ 0307 zcam05072 Did not execute due to arm fault 0307 zcam08333 More hardware in frame than expected due to arm fault 0308 zcam00056 Incorrect merge products due to arm fault, merged sol 296 zcam05076 instead of 307 zcam05072 0308 zcam00064 Out of focus due to command error 0308 zcam00065 Out of focus due to command error 0346 zcam03314 Too saturated to pull spectra 0347 zcam03316 ZR images out of focus due to command error 0353 zcam08382 Mispointed, drive timed-out before predicted end of drive 0353 zcam03319 Mispointed, drive timed-out before predicted end of drive 0356 zcam08384 Mispointed, rim of crater is cutoff 0359 zcam08389 Mispointed, drive timed-out before predicted end of drive 0374 zcam05068 Did not execute due to arm fault 0374 zcam05069 Did not execute due to arm fault 0374 zcam05070 Did not execute due to arm fault 0374 zcam05071 Did not execute due to arm fault 0375 zcam00003 Did not execute due to arm fault 0375 zcam05072 3 instances of zcam05072 did not execute due to arm fault 0375 zcam00050 Incorrect merge products due to arm fault, merged sol 332 zcam05072 instead of 375 zcam5072 0384 zcam03337 Mispointed, drive timed-out before predicted end of drive 0384 zcam08412 Mispointed, drive timed-out before predicted end of drive 0385 zcam03338 Mispointed, drive timed-out before predicted end of drive 0385 zcam03339 Mispointed, over-shot the target 0385 zcam08413 Mispointed, drive timed-out before predicted end of drive 0385 zcam08414 Mispointed, drive timed-out before predicted end of drive 0401 zcam05100 Partially mispointed 0401 zcam05101 Mispointed, descent stage hardware is obstructed 6. Browse products The current browse_asu products use unbayered data to generate the png. Some artifacts due to wavelength response are to be expected. These will be addressed in future releases. ------------------------------------------------------------------------------- Release Number:3 Release Date: 2022-03-22 Data Coverage: 2021-08-22 through 2021-12-22 (Sols 180 to 299) New products have been added to these collections: urn:nasa:pds:mars2020_mastcamz_sci_calibrated:data urn:nasa:pds:mars2020_mastcamz_sci_calibrated:browse urn:nasa:pds:mars2020_mastcamz_sci_calibrated:document Products have been revised in these collections: urn:nasa:pds:mars2020_mastcamz_sci_calibrated:document 1. General comments The Mastcam-Z release 1 filename matching document (mastcamz_release1_image_mapping.csv) has been revised and delivered with this release. This will serve as a guide from data downloaded from the old bundle structure prior to the release 2 revision of sol 0-89 products. There are 3 sols(193, 208, 209) which have thumbnail products (instead of the full resolution image), where the image products were deleted from the camera DEA (memory) prior to downlinking. Mars solar conjunction occurred over sols 216 to 235. During this time no sequences were executed due to DSN downlink availability. Zstack merge products for sols 192(zcam00050), 196(zcam00056) & 297(zcam00060) were RAD calibrated but were not IOF calibrated. These products get merged onboard the rover in the DEA as a new product (EZS) from the associated EDRs and the non-merged products are available in both RAD and IOF. 2. Recovered products There are several sols with products which were recovered from the rover at different encoding (ex. JPEG 50 vs uncompressed) or were recovered tactically. Recovered products were downlinked for imaging and video sequences and are distinguishable through the label (Ex. a recovered right image will have MczRRecoveredProduct in the label where the original (non-recovered) image has MczRImage). Sols Sequences ----- --------- 181 zcam08199 156 zcam07221 193 zcam05085 207 zcam08236 208 zcam08237 208 zcam08238 208 zcam08240 209 zcam08242 For every recovered product there is a corresponding identical non-recovered product (Thumbnail or full resolution image). 3. Cloned products There are several sols with products which were cloned from the rover at different encoding (ex. JPEG 50 vs uncompressed) or were recovered tactically. Cloned products were downlinked for imaging and video sequences and are virtually indistinguishable through the label (Ex. a cloned right image will have MczRImage in the label where the original (non-cloned) image also has MczRImage). Sols Sequences ---- --------- 238 zcam08261 237 zcam05086 264 zcam01004 279 zcam01005 For every cloned product there is a corresponding identical non-cloned product (full resolution image). 4.

New products have been added to these collections: urn:nasa:pds:mars2020_mastcamz_sci_calibrated:data urn:nasa:pds:mars2020_mastcamz_sci_calibrated:browse urn:nasa:pds:mars2020_mastcamz_sci_calibrated:document urn:nasa:pds:mars2020_mastcamz_sci_calibrated:miscellaeneous Products have been revised in these collections: None. 1. General comments This release has a new bundle structure to better accommodate all of the Mastcam-Z data products. The old bundle urn:nasa:pds:mars2020_mastcamz has been broken down into 6 bundles with all of Mastcam-Z ASU calibrated products in this bundle urn:nasa:pds:mars2020_mastcamz_sci_calibrated including associated documentation. The first release was entirely reprocessed at all levels (EDR, RAD etc..) due to a filename issue where the sclk was misreported in the filenames. Sols 9-55 were affected and release 2 includes all of the reprocessed release 1 data (sols 0-89). The RAD calibration process was also updated with: new shutter frame model coefficients, ODL header updates, improved sky flats, improved flat fielding for the solar filters. 2. Recovered products There are several sols with products which were recovered from the rover at different encoding (ex. JPEG 50 vs uncompressed) or were recovered tactically. Recovered products were downlinked for imaging and video sequences and are distinguishable through the label (Ex. a recovered right image will have MczRRecoveredProduct in the label where the original (non-recovered) image has MczRImage). Sols Sequences ----- --------- 0058 zcam05032 0061 zcam05036 0136 zcam08143 For every recovered product there is a corresponding identical non-recovered product (full resolution image). 3.

The actual zoom position count value can be found in the ZOOM_POSITION_COUNT keyword or by looking in the label of the first image acquired in the sequence. COMMANDED_FOCAL_LENGTH This can incorrectly report as "26.0 " when commanded in a group of images where all products are using the same focal length. The actual focal length value can be found in the FOCAL_LENGTH keyword or by looking in the label of the first image acquired in the sequence. INSTRUMENT_FOCUS_MODE This keyword is unreliable. To determine if an image was commanded using manual or autofocus you should look to the INSTRUMENT_FOCUS_STEPS and INSTRUMENT_FOCUS_STEP_SIZE keywords. If “INSTRUMENT_FOCUS_STEPS = 1” and “INSTRUMENT_FOCUS_STEP_SIZE = 6” The image was commanded using manual focus, if “INSTRUMENT_FOCUS_STEPS = 0” and “INSTRUMENT_FOCUS_STEP_SIZE = 0” there is no change from the previous image in a sequence and you should look to the first image acquired in the sequence, otherwise it was commanded using autofocus. Four keywords in the ODL3 label and are not present in the PDS4 XML label. NONLINEAR_PIXEL_THRESH NONLINEAR_THRESH SATURATED_PIXEL_THRESH SATURATED_THRESH 4. Known product issues There are two different products (Video vs Recovered Video) with a matching filename. The A06 version is a video product and the A05 is a recovered video product. The recovered products listed below are not in the archive since PDS archives the highest version available. This is a JPL pipeline issue and will be fixed in a future release. The Video product does have the same scene and same compression as the Recovered Video.

General comments Only RAD calibrated products have been included in this release, IOF calibrated products will be available in the second release. There are 9 sols(49,50,55,58,61,64,68,69,76) which have thumbnail products (instead of the full resolution image), where the video image products were deleted from the camera DEA (memory) prior to downlinking. Some image filenames in sols 1,2,3,and 4 have 'AUT' in place of 'ZCAM'. This is a known idio of cruise flight software. To determine the sequence, see the filename and label of the first image acquired. These products also have 'Scidata' in place of 'Image; in the labels. 2. Recovered products There are several sols with products which were recovered from the rover at different encoding (JPEG 50 vs uncompressed) or were recovered tactically. Recovered products were downlinked for imaging and video sequences and are distinguishable through the label (Ex. a recovered right image will have MczRRecoveredProduct in the label where the image has MczRImage).

Known label keyword issues Known label keyword issues are present for all sols in this release. The following ODL3 label keywords can report incorrect values when sequences are built using the first image to set up the commanding and indicate no change for the images that follow. ODL3 Keyword Description ------------------------------ --------------------------------- INSTRUMENT_ZOOM_POSITION_COUNT This can incorrectly report as "0" when commanded in a group of images where all products are using the same zoom position. The actual zoom position count value can be found in the ZOOM_POSITION_COUNT keyword or by looking in the label of the first image acquired in the sequence. COMMANDED_FOCAL_LENGTH This can incorrectly report as "26.0 " when commanded in a group of images where all products are using the same focal length. The actual focal length value can be found in the FOCAL_LENGTH keyword or by looking in the label of the first image acquired in the sequence. INSTRUMENT_FOCUS_MODE This keyword is unreliable. To determine if an image was commanded using manual or autofocus you should look to the INSTRUMENT_FOCUS_STEPS and INSTRUMENT_FOCUS_STEP_SIZE keywords. If “INSTRUMENT_FOCUS_STEPS = 1” and “INSTRUMENT_FOCUS_STEP_SIZE = 6” The image was commanded using manual focus, if “INSTRUMENT_FOCUS_STEPS = 0” and “INSTRUMENT_FOCUS_STEP_SIZE = 0” there is no change from the previous image in a sequence and you should look to the first image acquired in the sequence, otherwise it was commanded using autofocus.

General comments If you have any questions regarding the content of this archive reach out via email : mcz-pds@asu.edu There is visible charge buildup in the first few frames of a video sequence. This is understood and expected behavior. There are sols which have thumbnail products (instead of the full resolution image), where the image products were deleted from the camera DEA (memory) prior to downlinking. These sols are noted in the corresponding release section for affected sol. Some image filenames in sols 1,2,3,and 4 have 'AUT' in place of 'ZCAM'. This is a known idio of cruise flight software. To determine the sequence, see the filename and label of the first image acquired. These products also have 'Scidata' in place of 'Image' in the labels. Some IOF calibrated products appear to be more yellow. This is a known issue from the caltarget used for calibration. This does not affect the validity of the product and will be corrected in a future release.
