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:Cycle_map
This table maps cycle identifiers to various other time related ranges such as orbit ranges, dates, or LS. Note: This table is currently a stop gap measure to allow some automated procedures to gather cycle information. It is likely that the structure of this table may change in the future and some fields will probably be moved/removed. It is highly likely that the LS range will be removed.

Field Description Type Null Limits Size Key Default Authority Source
ID The cycle number. Note: Since the cycles are already identified by an integer value, the ID field is the integer value for the cycle, this is not an autoincrement field like most of the other tables in the database. INT(5) Not Null Primary Key State File
HITS The targeting specialist for this cycle. VARCHAR(25) HiTS
CIPP The Co-I of the Pay Period for this cycle. VARCHAR(25) CIPP
START_ORBIT The orbit the cycle begins executing on. INT(10) State File
END_ORBIT The orbit the cycle completes execution. INT(10) State File
CONFIRMED A value of zero in this field indicates that the information in the record is preliminary, and subject to being updated as more cycle information becomes available. A value of 1 indicates that the information has been confirmed, most likely by a HiTS. TINYINT(1) Cycle Editing Tool
LAST_UPDATE The date and time a record was last updated. TIMESTAMP DB Server
