AstroDrizzle is new software for aligning and drizzling HST images, with improved handling of astrometry. It is a major revision of the older, widely-used MultiDrizzle task. This new software brings an array of new features and algorithmic improvements, including the resolution of several known bugs in the MultiDrizzle software.
DrizzlePac, a suite of tasks that includes AstroDrizzle, will be officially released in June 2012. It replaces the STSDAS Dither package.
This software is currently available under IRAFX for preliminary testing. IRAFX contains code under development, and users should be aware that even though the software is presumed to be reliable, it has not been fully tested. At this time, we do not have the resources to provide support for DrizzlePac software. However, if you encounter any problems while using it, we would like to hear about it. To access DrizzlePac, you will have to install IRAFX, available at stsdas.stsci.edu/irafx.
