LAMOST Data Release 9 V1.1 includes spectra and catalogs obtained by LAMOST low/medium resolution survey during October 24th 2011 and June 12th 2021. For the low resolution survey, there are 5,533 plates observed, and 11,211,028 spectra are obtained in total; there are 10,893,354 stellar spectra, 241,454 galaxy spectra, 76,220 quasar spectra. There are seven spectroscopic parameters catalogs, including the LAMOST LRS General Catalog, the LAMOST LRS A, F, G and K Type Star catalog, the LAMOST LRS A Type Star Catalog, the LAMOST LRS M Type Star Catalog, the LAMOST LRS Observed Plate Information Catalog, and the LAMOST LRS Input Catalog respectively. For the medium resolution survey, there are 8,259,362 spectra in 1,529 observation plates, among them 1,846,438 non time-domain spectra, 6,384,475 time-domain spectra. In addition, there are four catalogues: medium resolution general catalog, medium resolution parameter catalog, medium resolution observed plate information catalog, medium resolution multiple epoch catalog and medium resolution input catalog.
