HDF Plans for Reprocessing:


The initial data reduction for the HDF was done rapidly, with many procedures and calibration files that had not been tested previously on HST data. While this preliminary set of reduced data will probably serve most of the immediate scientific needs, the final quality of the images and the accuracy of the photometry can be improved with some careful reprocessing. The data will be reprocessed over the coming months with improved calibration files, and with slightly different procedures for stacking the images. These differences are outlined below.
