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:Color_Processing_Statistics
Stores statistics on the corrections made to the data during color processing.

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
FILTER The color filter for which the statistics apply. ENUM("BG","RED","IR") Not Null Pipelines
HICOLORNORM_RATIO_CORRECTION_STANDARD_DEVIATION The standard deviation of the column corrections applied by the ISIS cubenorm program in the HiColorNorm Pipeline. This is the correction applied to the BG or IR to RED filter ratio product. FLOAT HiColorNorm
MINIMUM_PIXEL_LINE The line where the minimum valued pixel occurs in within the filter. INT(10) unsigned HiRat Pipeline
MINIMUM_PIXEL_SAMPLE The sample where the minimum valued pixel occurs within the filter. INT(10) unsigned HiRat Pipeline
PIXEL_VALUE_IR The I/F value of the pixel at the minimum line and sample in the IR filter. A null value here with non-null minimum line/sample column indicates that the pixel is an ISIS special pixel for the band at this location. DOUBLE(18,15) HiRat Pipeline
PIXEL_VALUE_RED The I/F value of the pixel at the minimum line and sample in the RED filter. A null value here with non-null minimum line/sample column indicates that the pixel is an ISIS special pixel for the band at this location. DOUBLE(18,15) HiRat Pipeline
PIXEL_VALUE_BG The I/F value of the pixel at the minimum line and sample in the BG filter. A null value here with non-null minimum line/sample column indicates that the pixel is an ISIS special pixel for the band at this location. DOUBLE(18,15) HiRat Pipeline
LAST_UPDATE The date and time the record was last updated. TIMESTAMP db server
