dp2-image-simulations

• imSim provides GalSim modules for simulating the Rubin observatory telescope and survey
• seacliff will provide GalSim modules for interfacing with Rubin DM products

from PVI

• Goal is to test the DM pipelines for shear calibration
• Galaxy models will be morphologically simple

from coadd

• Goal is to calibrate astrophysical effects, including the impact of blending on the effective redshift distribution for lensing
• Galaxy models will come from forced photometry of COSMOS observations¹
• The Milky Way stellar population model will come from TRILEGAL²
• Simulations will cover the full DP2 footprint
• Simulations will feature four shear configurations: positive/negative shear in both shear axes, centered at each cell
