Abstract

This poster presents a guide to using the new MultiDrizzle Pyraf script to combine sets of dithered WFPC2 images. The MultiDrizzle script has condensed the steps of drizzling multiple images, as shown in the HST Dither Handbook (Koekemoer, et al. 2002), into a single Pyraf command with a number of parameters governing its behavior. This is aimed at greatly improving the ease with which images can be registered, cleaned of cosmic rays, and combined together using drizzle and related tasks. Images that have been produced using MultiDrizzle to combine WFPC2 datasets from the Dither Handbook examples are presented, and the results from a variety of parameter settings are explained and compared.
