HiCat Data Dictionary

Catalog: HiRISE
The main HiRISE catalog contains all the information used in operating the HiRISE camera after it is attached to the MRO spacecraft. The information is divided into those related to suggesting, planning, commanding, retrieving, processing, validating, and distributing the observations. The tag that follows an observation through all these catalogs (and from Earth to Mars and back) is the unique Observation_ID. This text representation also forms the core of the product names. The HiRISE catalog also contains ancillary information needed in various uplink and downlink activities, such as the people making image suggestions, MRO project uplink files, SPICE and engineering data, and public image releases.
Table:CCD_Processing_Statistics
Stores statistics on the corrections made to the data to match the channels in each CCD and to match the CCDs radiometrically.

Field Description Type Null Limits Size Key Default Authority Source
ID A unique record identifying integer. INT(10) unsigned auto_increment Not Null Primary Key db server
OBSERVATION_ID The observation ID of the data for which these statistics apply. VARCHAR(25) Not Null Pipelines
CCD The CCD the corrections apply to. ENUM("RED0","RED1","RED2","RED3","RED4","RED5","RED6","RED7","RED8", "RED9","IR10","IR11","BG12","BG13") Not Null Pipelines
CONTROL_CHANNEL The CCD channel used as the control when determining the CHANNEL_MATCHING_CORRECTION. INT(1) HiStitch
CHANNEL_MATCHING_CORRECTION The multiplicative correction used to match one CCD channel to the other. This correction is applied to the channel that is not the control channel. DOUBLE HiStitch
RADIOMETRIC_MATCHING_CORRECTION A multiplicative correction applied to each CCD to radiometrically match the CCDs. For a given observation, the CCD's are matched to the one CCD that has a correction value of 1.0. DOUBLE HiccdStitch
LEFT_OVERLAP_AVERAGE The average value of the left overlap region of the CCD. DOUBLE HiccdStitch
RIGHT_OVERLAP_AVERAGE The average value of the right overlap region of the CCD. DOUBLE HiccdStitch
CUBENORM_COLUMN_CORRECTION_STANDARD_DEVIATION The standard deviation of the column correction applied to observations that go through the HiccdStitchC pipeline. This value will be null for observations that don't go through HiccdStitchC. DOUBLE HiccdStitchC
LAST_UPDATE Records the time when the record was last updated. TIMESTAMP db server
