1.1 Introduction
This DrizzlePac Handbook is written for both novice users and seasoned "drizzlers." Users new to HST data processing and analysis are recommended to familiarize themselves with HST data formats and install the newest version of DrizzlePac with Python 3 from PyPI (pip install drizzlepac) or via stenv. The latest installation instructions for stenv can be found here.
The HST Data Handbook Introduction is a good place to start for information about HST data, and instructions for getting ready to use DrizzlePac are provided here. For work on a specific instrument, a review of the instrument's data handbook is recommended.
IRAF/PyRAF has been deprecated and is not supported. Please use the latest version of DrizzlePac with Python 3.
All the code in this document is in Python 3. For those who are switching from PyRAF/IRAF, this newsletter from 2018 explains the motivation behind this transition and contains resources on how best to make the change, including information about the STAK tutorial documentation which provides Python alternatives to many commonly used PyRAF/IRAF tools.
