AstroDrizzle: More than a New MultiDrizzle

http://drizzlepac.stsci.edu/ AstroDrizzle is new software for aligning and drizzling Hubble Space Telescope images. It is a substantial improvement on the current MultiDrizzle with a particular enhancement on the handling of astrometry. This software is part of the new STSDAS package DrizzlePac, a suite of tasks that will replace the STSDAS Dither package. This package allows the user to do a lot more than simply combine their HST images with high photometric and astrometric fidelity. We present examples based on HST images that show how the tasks in this package now provide a new paradigm for working with the world coordinate system of these images, for aligning the images and for combining them with AstroDrizzle to produce the best possible HST science. The details of the combined images generated by AstroDrizzle are also discussed to illustrate how the provenance of the final product now gets maintained.
