Abstract

From 2006 to 2008, all sub-mirrors and instruments of LAMOST will be installed gradually until fully completion. Before all sub-mirrors and instruments installed, LAMOST team planed a temporary scheme in order to do some testing observations. The plan will start from the beginning of 2007, and the part LAMOST will have 3×3 Mirrors (3 sub Ma and 3 sub Mb) with 1.25 degree field, and 250 fibers on its focal plane at that time. We are planning a set of observations during the engineering process, which includes small amount of stars. The spectral resolution will be 10000 and 2000, and the amount of spectra in the data set will reach several thousands. By using these data, we can improve our techniques of automated reduction and analyzing. For example, in order to test our software, physical parameters of a small proportion of stars such as Vr, Teff, log g, [Fe/H], [α/Fe] should be compared with Sloan Digital Sky Survey (SDSS). If the results are precise enough, the parameters of more stars could be applied to do some research, such as searching for star stream, studying star clusters in our Galaxy, and searching for poor-metal star etc.
