Roman DC2 Simulated Image (Troxel 2023) Overview
Roman DC2 Simulated Image Overview Roman DC2 Simulated Image Data Access


Troxel et al. (2023) simulated 20 square degrees of overlapping synthetic imaging surveys representing the full depth of the Nancy Grace Roman Space Telescope High-Latitude Imaging Survey (HLIS) observing the Dark Energy Science Collaboration (DESC) Data Challenge 2 (DC2) universe. They simulate for the first time fully chromatic images along with the detailed physics of the Sensor Chip Assemblies derived from lab measurements using the flight detectors. The simulated imaging and resulting pixel-level measurements of photometric properties of objects span a wavelength range of ~0.3 to 2.0 microns.
