Abstract
A convention for storing distortion information in HST images was developed and implemented in two software packages - PyWCS and STWCS. These changes allow the development of a WCS based version of Multidrizzle, released now as AstroDrizzle, and image alignment software, released as tweakreg. The distribution of WCS solutions is discussed.
