Supplemental WFPC2 CYCLE 16 Intflat Linearity Check and Filter Rotation Anomaly Monitor
Abstract
Supplemental observations to 11029, to cover period from Aug 08 to SM4. Intflat observations will be taken to provide a linearity check: the linearity test consists of a series of intflats in F555W, in each gain and each shutter. A combination of intflats, visflats, and earthflats will be used to check therepeatability of filter wheel motions. {Intflat sequences tied to decons, visits 1-18 in prop 10363, havebeen moved to the cycle 15 decon proposal 11022 for easier scheduling.}Note: long-exposure WFPC2 intflats must be scheduled during ACS anneals to prevent stray light from the WFPC2 lamps from contaminating long ACS external exposures.Note: These are supplemental observations to cover June to SM4 {oct 8 '08} + 6 months.
