References for data used in current DOLPHOT module

- Zero Points: Provided 11/16 from the STScI help desk
- PSFs: Generated using WebbPSF version 1.2.1 using distorted PSF models.  Key inputs for these PSFs were time-dependent OPD maps from 7/24/2022, 5x oversampling, and an input spectrum of a G5V model from the Phoenix stellar library. Input spectrum is sampled over 21 points for broadband filters, 9 points for medium band and 5 points for narrow band filters.
- Encircled Energy: Calculated from the PSFs
- Distortions: Stage 2 files contain distortion data, but UseWCS=2 is required to make use of this
- Pixel Area: N/A - Stage 2 FITS files contain PAM data
- Gain: downloaded 11/03/22 from https://jwst-docs.stsci.edu/jwst-near-infrared-imager-and-slitless-spectrograph/niriss-instrumentation/niriss-detector-overview
- Readout noise: CDS value of 16.8 e- obtained via help desk on 11/03/22.  Note this is divided internally by sqrt(2) as the CDS read noise values are based on two images.
- Data quality: downloaded 10/11/22 from https://jwst-pipeline.readthedocs.io/en/latest/jwst/references_general/references_general.html
