Scheduler, survey strategy analysis, and other simulation tools for Rubin Observatory.
The Legacy Survey of Space and Time (LSST)
is anticipated to encompass around 2 million observations spanning a decade,
averaging 800 visits per night. The rubin_sim package was built to help
understand the predicted performance of the LSST.
The rubin_sim package contains the following main modules:
phot_utils- provides synthetic photometry using provided throughput curves based on current predicted performance.skybrightnessincorporates the ESO sky model, modified to match measured sky conditions at the LSST site, including an addition of a model for twilight skybrightness. This is used to generate the pre-calculated skybrightness data used inrubin_scheduler.skybrightness_pre.moving_objectsprovides a way to generate synthetic observations of moving objects, based on how they would appear in pointing databases ("opsims") created byrubin_scheduler.mafthe Metrics Analysis Framework, enabling efficient and scientifically varied evaluation of the LSST survey strategy and progress by providing a framework to enable these metrics to run in a standardized way on opsim outputs.
More documentation for rubin_sim is available at
https://rubin-sim.lsst.io, including installation instructions.
