1. Extract information about the instrument, exposure start time and spacecraft
... NOTE that this call also sets the state of the cal to the returned instrument. The and are obtained from respectively from the INSTRUME and DATE-OBS keywords of the dataset header. The is read from the RA_PNT , DEC_PNT and PA_PNT keywords (this is actually wrong, since the instrument attitude is what should be stored in these, not the spacecraft attitude). The boresight is then obtained for the exposure start time, and calculated by applying the boresight rotation to . ...
