Rubin M1M3 Dynamic performance : stability and actuation during operations
HyeYun Park, Petr Kubánek, Kshitija Kelkar +20
The Vera C. Rubin Observatory is preparing to commence the Legacy Survey of Space and Time with the fully integrated Simonyi Survey Telescope. To verify that the primary/tertiary (…
An overview of stray light findings and interpretation during on-sky commissioning of LSSTCam
Gabriele Rodeghiero, Alex Drlica-Wagner, Alessio Taranto +78
Wide-field telescopes are intrinsically difficult to shield from unwanted stray and scattered light, while the search to identify sources of contaminating light is frequently a cha…
Investigation and Mitigation of a Prominent Off-Axis Stray Light Path in Rubin Observatory Commissioning
Alex Drlica-Wagner, Alessio Taranto, Gabriele Rodeghiero +12
The "scratched tape" stray light feature is the most prominent and prevalent stray light artifact identified during the commissioning of the Vera C. Rubin Observatory. The scratche…
