STIS-16 CCD Image and Pointing Stability
Abstract
Check image motion using external star field and internal aperture illuminated by lamp. Images of star field and 0.1x0.09 and 52x0.05 aperture are alternately recorded for two orbits. This activity is to be executed after large angle maneuver predicted to induce large thermal change that might affect focal plane-to-STIS and internal STIS optical stabilities. Advice should be sought from thermal engineers for worst-case thermal change. If possible, this activity will be done using an established astrometric star field, such as those in NGC 188 or M35.
