Aligning HST images with JHAT.
An example HST Dataset is downloaded, and then a series of alignment methods are used. For more information on the key parameters used for alignment see :ref:`params:Useful Parameters`.

Download some Data
For this example we download 2 HST DRZ images from MAST. They're the same filter and same field, just separated in time.

Create a Photometric Catalog for Relative Alignment
We choose one of the images to be the reference image, and then create a catalog that we will use to align the other image.
