MultiDrizzle automates and simplifies the detection of cosmic-rays and the combination of dithered observations using the Python scripting language and PyRAF, the Python-based interface to IRAF. MultiDrizzle was developed by the Science Software Branch at the Space Telescope Science Institute.

A new Multidrizzle Handbook has been written to describe the algorithms used by Multidrizzle, to provide instructions on how to run MultiDrizzle, to provide an extensive set of examples, and to describe the parameters used by MultiDrizzle. The Handbook can be accessed either as a static PDF document or as static HTML pages

Updates or corrections to the officially reviewed PDF or HTML documents can be found in What's New. This material has been developed since the last version of the Handbook was made available and includes material which can immediately benefit users of Multidrizzle. This material may change before the next version of the Multidrizzle Handbook gets produced, but represents the best current information available at the time.

You can download MultiDrizzle as part of the complete stsci_python package from our download page
