Good morning everyone. I am glad to give you an introduction of our project. My topic is the SSS system of LAMOST and Vincent is my name. I come from the Department of Modern Physics. First of all, I will give you some definitions involved in my presentation. The LAMOST was proposed by the Chinese Academy of Sciences (CAS), and was supported widely by astronomical community. The project will make substantial contribution to the study of extra-galactic astrophysics and cosmology, such as galaxies, quasars and the large-scale structure of the universe. This is the telescope. It's beautiful, is not it? The telescope will be located at the Xinglong station of Beijing Astronomical Observatory, Its construction period is 10 years, coming into operation at the end of 2007 The Lamost Will Observe Around 10 Million Spectra from Targets Distributed Over An Area of About 24 THOUSAND SQUARE DEGREES, USING A MULTI-Object Fiber SP ectrograph that can simultaneously observe 4000 objects in a circular field of view 5 degree in radius. That's great! You know, the traditional telescope could only observe one target while The LAMOST can observe 4000 objects simultaneously! However, large surveys using multi-object spectrographs require automated methods for deciding how to efficiently point observations and how to assign targets to each pointing. This is the job of SSS system. So we designed an algorithm named "Highest density & averagely assign"
