SKYSURF VIII -- Modeling SKYSURF Completeness Data for Comparison to the Hubble Space Telescope Exposure Time Calculator

The study modeled galaxy completeness using Hubble Space Telescope data to assess measurement accuracy. They simulated objects and fitted models for exposure time and background effects, finding that existing Exposure Time Calculators (ETC) underestimate completeness limits by 1-2 magnitudes for extended galaxies.
