8.4 IIPH Files

Beware of occasional bumps in the IIPH during stable pointing that have been traced to the effects of cosmic-ray glitches in the star tracker's CCD. Recognition of events of this type may be helped by the fact that large apparent excursions in the pointing direction are not accompanied by the OTF going down.
