Scientific paper

The LSST will allow a wide variety of science to be done using data from a single survey. A large part of ensuring this claim is designing a smart and adaptive algorithm for scheduling observations, one which can effectively merge multiple requirements into a single program of observations while maximizing time on the sky and coping effectively with changing conditions in real time.
Diverse requirements include multiband imaging of 30,000 square degrees of sky, achieving a uniform depth of exposure across 20,000 square degrees in each of six filters, allowing effective search strategies for NEO's and shortand long-period variables, and providing frequent, deep exposures to characterize faint transients and moving objects.
The LSST operations simulator includes a detailed model of seeing and sky transparency derived from data obtained at its site on Cerro Pachon, Chile. It also includes a detailed model of the delays incurred by readout of the camera, filter changes, active optics acquisition, and movements of the dome and telescope.
We describe current progress in the LSST scheduler design and present simulations of a prototype ten-year LSST mission which demonstrate that all of the science requirements and constraints can be accomodated successfully into a single survey.
