Source Identification Options
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+-----------------------------
A number of options have been implemented within the catalog generation code in order
to best match the contents of the exposure, including presence of saturated sources and
cosmic-rays. The available options include:

Source Identification using DAOStarFinder
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+-----------------------------------------
We use the `photutils.detection.DAOStarFinder <https://photutils.readthedocs.io/en/stable/api/photutils.detection.DAOStarFinder.html>`_ Astropy tool to identify sources in the background-subtracted
multi-filter detection image. This would be where the background computed using one of the algorithms
discussed in Section 1.3 is applied to the science data to initialize point-source detection processing.

Source Identification using PSFs
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+--------------------------------
This option, introduced in Drizzlepac v3.3.0, drizzles model PSFs created using TinyTim to match the orientation and plate
scale of the observation to look for sources in the image. Where DAOFind convolves the image with a perfect Gaussian whose
FWHM has been specified by the user, this option convolves the image with the model PSF to identify all sources which most
