Description

No CCD cameras are perfect, which includes both HST and JWST. Each raw image has hot pixels. I recommend to remove them by applying darks to the raw images before counting the number of galaxies. This way, no hot pixels are considered as stars nor galaxies.

Research direction

Start in the repository's Jupyter Notebook and locate the steps that process raw images and count galaxies. Determine whether dark frames are available and how hot pixels are currently treated. Done means dark correction occurs before galaxy counting so hot pixels are not counted as stars or galaxies.
