The Dither Package software has been upgraded to include mosaicing of all 4 CCDs, as well as cosmic ray removal from single image pointings. These and other topics are reviewed. A set of formulae has been developed to correct for CTE loss, with dependencies on the X and Y positions, the background counts, the brightness of the star, and the time of the observation. In general, typical WFPC2 exposures are much longer than these short calibration images, resulting in higher background which significantly reduces the CTE loss and minimizes the CTE problem for most science exposures. The archive branch, in an effort to save resources, is planning to provide DADS paper products in electronic format only.
Help is available on the possible search fields.
This interface is not intended for general archive users but specifically for PIs of HST programs. The archive plans to stop printing paper products on August 1, but will still provide paper hard copies in case of special need. We are taking this opportunity to alert the community of the workshop and encourage all that are interested in participating to visit the WFC3 website for further details. The Space Telescope Science Institute currently has an opening for the position of WFPC2 Instrument Scientist. Work also includes updating the user documentation and WWW pages related to WFPC2.
