Description:
We totally published 9,026,365 targets in this table, including
8,183,160 stars, 152,863 galaxies, 52,453 quasars, and 637,889 unknown
objects. In addition, there are 5,808,985 objects with g band S/Ns
larger than 10, 7,701,235 objects with i band S/Ns larger than 10, and
5,734,239 objects with g band S/Ns larger than 10 and i band S/Ns
larger than 10.
On the website http://dr5.lamost.org/catalogue, we provide two format
LAMOST general catalogs, which include a FITS table and a CSV table,
and the two catalog files have the same contents.
