WFPC2 Technical Instrument Report 98-04:
Proposed Modification to the WFPC2 SAA Avoidance Contour
-Biretta and Baggett
We have examined cosmic ray rates taken inside and around the South Atlantic Anomaly (SAA). Based on those results, we propose a new, slightly smaller WFPC2 SAA avoidance region. The new SAA contour should help improve HST scheduling efficiency with minimum impact to WFPC2 observations.
