Welcome to the LSST Image Simulation Page

The Large Synoptic Survey Telescope (LSST) End to End Massive Simulator is a set of fast photon Monte Carlo codes and catalog building codes for simulating optical images as will be seen by  LSST. The image simulator generates photons from catalogs of astrophysical sources, refracts them as they travel through the atmosphere, follows them as they reflect and refract off the optics, and traces them into the detector.

The image simulation is currently attempting to address:

• Generating catalogs of stars and galaxies to a depth of r=28 with associated photometric and structural properities

• Generating high fidelity images of the sky (including the atmosphere, telescope and camera) for use by the Data Management group to test and evaluate the processing pipelines
