LAMOST DR7 V1.3 LRS General Catalog
LAMOST DR7 V1.3 LRS General Catalog lists parameters of spectra obtained by LAMOST low resolution survey during October 24th 2011 and June 8th 2019. For galaxy, QSO and M type stars, all of them are in the catalog. But for other type targets, only spectra with r band S/Ns larger than 2, or g band S/Ns larger than 5, or i band S/Ns larger than 5 are included. There are totally 10,640,255 spectral information in this table, including 9,881,260 stellar spectra, 198,393 galaxy spectra, 66,406 quasar spectra, and 494,196 unknown object spectra. In addition, there are 6,808,754 spectra with g band S/Ns larger than 10, and 9,097,648 spectra with i band S/Ns larger than 10, and 6,728,257 spectra with both g and i band S/Ns larger than 10. Two formats of the catalog, a FITS table and a CSV table, are available on the website http://dr7.lamost.org/v1.3/catalogue.
