Besides this change in the frequency of decons, we have not seen any appreciable change in the dark current performance. We also point-out the beautiful color images of Mars obtained on 10 March with the linear ramp filters by Crisp, et al. The current plan is to perform the next decontamination on 5 April. We will be releasing an Instrument Science Report detailing these and other results in the near future. This is probably a consequence of the slowing down of the OTA desorption trend, which thus far had necessitated a compensatory focus move roughly twice a year.
Early results indicate that the desired focus position was achieved.
No other focus moves are expected for the next 6-8 months. The WFPC2 group is in the process of designing the calibration plan to support Cycle 7 observations, and would like to solicit user input and suggestions. However, it is likely that some programs will be redesigned or augmented, while others may be scaled back or even discontinued. Specific comments on the relative importance of the various programs would be especially welcome. This list includes all preprints received by the STScI Library not yet published in the journals.
