This keyword indicates the source of the input to the spacecraft pointing calculation, which should be the pointing mnemonics (quaternions) retrieved from the Engineering database. If the required ENG_DB mnemonics are found within the time range of the exposure, the pointing information is calculated from them and this value is CALCULATED. If mnemonics are not found within the time range of the exposure, the pointing information is set to the planned target RA/Dec in the APT proposal and this value is PLANNED.
