Housekeeping file

The Housekeeping File (HKF) will contain time series of housekeeping data which describe the condition of the satellite and of the instruments. It will also contain the angular elevation of the satellite above the horizon, the Sun angle, the local geomagnetic rigidity, and flags to indicate whether the satellite is behind the Earth with respect to the Sun and whether the satellite attitude is changing. Information in the HKF comes from the FRF and from the AF and OF. The HKF will be organized like Space Telescope SDSDAS tables and be in FITS, the precise format TBD.
