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:Orbits
This table holds MRO orbital information related to specific orbits. These generally take the form of times (eg. the light-to-dark terminator crossing time, etc).

Field Description Type Null Limits Size Key Default Authority Source
ORBIT_NUMBER The MRO Orbit Number for which information is being stored. INT(10) unsigned Not Null Primary Key db server
DEQUAX_TIME The date and time of the descending equator crossing. This time is essentially the start time of the given orbit and occurs on the night side of Mars. DATETIME OPTG file
AEQUAX_TIME The date and time of the ascending equator crossing. This occurs on the day side of Mars. DATETIME OPTG file
NPOLEX_TIME North polar minimum slant range crossing time. DATETIME OPTG file
SPOLEX_TIME South polar minimum slant range crossing time. DATETIME OPTG file
LDTERM_TIME Light-dark terminator crossing time. DATETIME OPTG file
DLTERM_TIME Dark-light terminator crossing time. DATETIME OPTG file
ECLIPSE_START The eclipse start time when Mars is between MRO and the sun. DATETIME OPTG file
ECLIPSE_END The eclipse end time, when MRO moves out of Mars' shadow. DATETIME OPTG file
DEQUAX_LSUBS The solar longitude at the time of the descending equator crossing. DOUBLE Derived from OPTG time
LAST_UPDATE This column records the last time that a record was updated. TIMESTAMP db server
