In-situ measurements confirm ~2% reflectance for LSSTCam optics and simulations show optical ghosts impact ~0.57% of the focal plane averaged across bands.
Overview of stray light characterization, modeling with ray tracing, and mitigation during on-sky commissioning of the LSST Camera.
The authors report using Zephyr Scale to create test cases with step-by-step scripts, group them into daily test cycles, define review workflows, and integrate JSON-based tests with the observatory scheduler for commissioning and early operations.
