<p>This package supports the use of MultiDrizzle as an integrated set of modules that can be run in an automated manner to combine images. The version of MultiDrizzle described here implements a single task to run the entire MultiDrizzle processing pipeline, while also providing the framework for users to create their own custom pipeline based on the modules in this package merged with their own custom code if desired.</p>
<p>This package relies on the STWCS and PyWCS packages in order to provide the support for the WCS-based distortion models and alignment of the input images.</p>

<h2>DrizzlePac Release Notes<a class="headerlink" href="#drizzlepac-release-notes" title="Permalink to this headline">¶</a></h2>
<p>The code for this package gets released through a number of methods: namely, the use of the package for pipeline and archive processing of ACS and WFC3 data, SSB’s semi-annual public release of the stsci_python package, and a weekly beta release of the development version. The following notes provide some details on what has been revised for each version.</p>

<h2>Image Registration Tasks<a class="headerlink" href="#image-registration-tasks" title="Permalink to this headline">¶</a></h2>
<p>Documentation for the replacement task for IRAF’s <em class="xref py py-obj">tweakshifts</em>, currently named <em class="xref py py-obj">tweakreg</em>, has been added to this package. These new modules describe how to run the new TEAL-enabled task, as well as use the classes in the task to generate catalogs interactively for any chip and work with that catalog. The current implementation of this code relies on a very basic source finding algorithm loosely patterned after the DAOFIND algorithm and does not provide all the same features or outputs found in DAOFIND. The fitting algorithm also reproduces the fitting performed by IRAF’s <em class="xref py py-obj">geomap</em> in a limited fashion; primarily, without iterations of outliers and only to perform fits equivalent to <em class="xref py py-obj">geomap</em>‘s ‘shift’ and ‘rscale’ solutions. These algorithms will be upgraded as soon as replacements are available.</p>
