Description
In this talk, a review of the current status of data reduction pipeline of LAMOST and an overview of the updates to the 2D and 1D reduction procedures and the LAMOST stellar parameter pipeline (LASP) will be given. The different versions of the data releases will be compared, the access to the data will be introduced and the details of the data quality will be presented. Stellar parameters are measured for 5 million stars during the first phase of the LAMOST survey. Based on this large database, we performed a serious statistical study regarding the instrumental stability and intrinsic errors. Through machine learning and with the information from multi wavelength bands, we have discovered some interesting outliers in the large stellar parameter data base.
