Rover EMERGENCY images
The following ten Rover Camera EDRs all have COMMAND_SEQUENCE_NUMBER = 0. These images were taken autonomously while there was an error condition on the rover (OBSERVATION_NAME = EMERGENCY). They all have an IMAGE_ID of A000000 and are all missing a SOURCE_PRODUCT_ID.

Color camera EMERGENCY images
There were four instances when the rear camera acquired images in an emergency mode and erroneously compressed them. As a result, the color information was lost for these images, and they were therefore not converted to three-banded color images. The rear camera images which exist as single-banded images but which were not converted to three-banded images are the following:

RVR_EDR-1247199566-A000000-REAR

RVR_EDR-1249330855-A000000-REAR
Rover Camera EDRs missing first packet
The following five images were all missing their first packet. They are therefore missing values for EXPOSURE_DURATION, ROVER_HEADING, ROVER_POSITION, and LINEAR_ACCELEROMETER.

Rover Camera EDRs missing IMAGE_IDs
In addition to missing their first packet, the following two images were also missing their IMAGE_IDs. (No SPICE e-kernals were available for these images.) Their COMMAND_SEQUENCE_NUMBERs are shown along with the PRODUCT_IDs.

RVR_EDR-1253323568--LEFT 75030
RVR_EDR-1253404503--LEFT 75077
Rover Camera MIDRs constructed from EDRs missing first packet
The following mosaics include EDRs which were missing their first packet. These products have inherited all of the missing values of their parent products.

Rover Camera EDRs missing values in PDS label
The following images (triple- and single-banded versions, respectively, of the same image) have valid index table information, but for some unknown reason this information is not in the image labels. The missing values are provided here:

RVR_EDR-1247210909--COLOR
RVR_EDR-1247210909--REAR
IMAGE_ID = "S005578"
ROVER_HEADING = 40297
ROVER_POSITION = (4.7270, -3.2800)
Non-standard file extensions for rover uplink reports.
There are ASCII documents in the DOCUMENT/ROVERDOC/UPLKLOGS/FLIGHT subdirectories that do not have ".ASC" extensions; multiple extensions were required to distinguish various different reports with the same command sequence number.
Rover image status report incomplete.
The Rover image status report contained in the DOCUMENT/ROVERDOC/DOWNLINK/TABLIMAG.HTM file is missing some images.
Typographical errors in APXS_SIS
Sections 2.2.1 and 2.2.2: "hexidecimal" should be "hexadecimal" (Adobe PDF version only)
Figure 2.5 identifies file extension for APXS EDRs as ".DAT"; it should be ".TAB" (Adobe PDF and HTML versions)
Appendix A.1 includes SOURCE_PRODUCT_ID as a keyword found in the APXS EDR labels, which it is not (Adobe PDF version only)
