10.2 Auxiliary quantity calculation
Auxiliary quantities are defined here as some interesting parameters which are
not contained in the distributed FOTs but are computed using information contained
therein (namely using attitude and ephemeris data).
The command saxauxcalc produces five time profiles with one second resolution,
spanning the entire observing period. The time profiles have fixed names and content.
The pointtype.time file is the one normally used to make time windows.
- bright.time, the angle between the NFI axis and the bright Earth
- earth.time, the angle between the NFI axis and the Earth
- pointtype.time, the pointing flag, defined as
- 0 for a normal pointing (NFI looking at the target in the sky)
- 1 NFI looking at the bright Earth
- 2 NFI looking at the dark Earth
- rigidity.time, the magnetic rigidity
- sunangle.time, the sun aspect angle
