PDS Terminology

Data Set Types

ABR
The ABR is derived from band 3 of a VIS-RDR QUBE (or first available band of the highest calibration product available).

AEDR
Aggregated Experiment Data Record

Calib
May be either Calibration Data or Calibrated Data.

Calibration data are those that are collected with the science instrument or in conjunction with a specific set of measurements, and which are used to translate raw data numbers generated by the instrument into meaningful units.

Calibrated data are science data generated by the instrument which have been corrected so that the values are expressed in or are proportional to some physical unit such as radiance. These data have not been resampled, so the edited data can still be reconstructed.

DDR
Derived Data Record - a product that has been derived from EDRs or RDRs by averaging, binning, sampling, etc.

DIM
Digital Imaging Model

DSDP
Decompressed Standard Data Product

DTM
Digital Terrain Model

EDR
Experiment Data Record - Space science data that may have been corrected for telemetry errors and split or decommutated into a data set for a given instrument. Data may be tagged with time and location of acquisition. This data usually corresponds to CODMAC level 2 or NASA level 0 products.

MDR
Master Data Record - All telemetry ordered by time. Occasionally MDRs are broken into video MDRs, science MDRs, and engineering MDRs.

MIDR
Mosaicked Image Data Record - created by combining multiple EDRs; may also be geometrically and/or radiometrically corrected.

ODR
Original Data Record - Telemetry data with space science data embedded. ODRs are often recycled during processing and not retained.

For Magellan, the ODR came out of the telemetry system. Magellan retained the ODRs.

PEDR
Precision Experiment Data Record

QUBE

RDR
Reduced Data Record - a product that has been converted from the raw data counts returned from the spacecraft into units like degrees or meters.

REDR
Raw Experiment Data Record

SAMPLER
Sample data from a data set (as opposed to sub-sampled data).

SEDR
Supplementary Experiment Data Record - Non-science data associated with a data set; it is useful in interpreting data and consists of instrument gains, offset, pointing information for scan platforms, etc.

SHGADR
Spherical Harmonics Gravity ASCII Data Record

TDR
