Abstract:
The Large sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)
general survey is a spectroscopic survey that will eventually cover
approximately half of the celestial sphere and collect 10 million
spectra of stars, galaxies and QSOs. Objects in both the pilot survey
and the first year regular survey are included in the LAMOST DR1. The
pilot survey started in October 2011 and ended in June 2012, and the
data have been released to the public as the LAMOST Pilot Data Release
in August 2012. The regular survey started in September 2012, and
completed its first year of operation in June 2013. The LAMOST DR1
includes a total of 1202 plates containing 2955336 spectra, of which
1790879 spectra have observed signal-to-noise ratio (SNR)≥10.
All data with SNR≥2 are formally released as LAMOST DR1 under the
LAMOST data policy. This data release contains a total of 2204696
spectra, of which 1944329 are stellar spectra, 12082 are galaxy
spectra and 5017 are quasars. The DR1 not only includes spectra, but
also three stellar catalogs with measured parameters: late A,FGK-type
stars with high quality spectra (1061918 entries), A-type stars
(100073 entries), and M-type stars (121522 entries). This paper
introduces the survey design, the observational and instrumental
limitations, data reduction and analysis, and some caveats. A
description of the FITS structure of spectral files and parameter
catalogs is also provided.
Description:
The LAMOST general catalog includes 717469 objects obtained from the
LAMOST pilot survey, which contain 648746 stars, 2723 galaxies, 621
quasars and 65406 unknown objects, and 1487200 objects obtained
from the LAMOST general survey, which contain 1295583 stars, 9359
galaxies, 4396 quasars and 177862 unknown objects, so this catalog
totally includes 2204696 objects including 1,944,329 stars, 12082
galaxies, 5017 quasars and 243268 unknown objects. In this catalog,
there are 1186132 objects with SNR of g band larger than 10,
1680794 objects with SNR of i band larger than 10, and 1746202
objects with SNR of g band larger than 10 and SNR of i band larger
than 10.
