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.
Description:
There are a couple of corrections been made in this releasing:
Recalculated all the errors of Teff, Logg, Fe/H and rv in the AFGK
catalog. Refer to the DR2 paper (in preparation) for details.
Compare to the previous internal releasing, some extra spectra has
been added into this version of releasing: STAR from 3,779,597 to
3,843,597, increased 63,923; GALAXY from 37,665 to 47,036, increased
9,371; QSO from 8,633 to 13,262, increased 4,629.
The major contribution to this increasing is that we applied a new
method to reduce the data which previously was abandoned due to lack
of standard stars with high enough S/N. Refer to the paper 'LAMOST
Spectrograph Response Curves: Stability and Application to flux
calibration' (in preparation) for details.
There are also a small amount of increasing is due to the correction
of fiber flag, and to the eye check work, etc.
