Sky subtraction is the key technique in data reduction of multi-fiber spectra. Knowledge of the related instrument character is necessary to determine the method adopted in sky subtraction. In this study, we described the sky subtraction method designed for LAMOST(Large sky Area Multi-Object fiber Spectroscopic Telescope) survey. The method has been intergrated into LAMOST 2D Pipeline v2.6 and applied to data of LAMOST DR3 and later. For LAMOST, sky emission line calibration is used to… Expand
The LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap. I. The Spectroscopic Redshift Catalog
We present a spectroscopic redshift catalog from the LAMOST Complete Spectroscopic Survey of Pointing Area (LaCoSSPAr) in the Southern Galactic Cap (SGC), which is designed to observe all sourcesExpand
The LAMOST middle resolution spectrograph
The LAMOST completed its first five years of operation in June 2017, and 9 million low resolution spectra are obtained. The spectrographs have been upgraded in 2017, and the resolution can reach upExpand
The galaxy luminosity function in the LAMOST Complete Spectroscopic Survey of Pointing Area at the Southern Galactic Cap
We present optical luminosity functions (LFs) of galaxies in the $^{0.1}g$, $^{0.1}r$, and $^{0.1}i$ bands, calculated using data in $\sim 40$ $deg^{2}$ sky area of LAMOST Complete SpectroscopicExpand
A wide star–black-hole binary system from radial-velocity measurements
Radial-velocity measurements of a Galactic B-type star show a dark companion that seems to be a black hole of about 68 solar masses, in a widely spaced binary system. Expand
The first data release of LAMOST low-resolution single-epoch spectra
LAMOST Data Release 5, covering ∼17 000 deg2 from –10° to 80° in declination, contains 9 million co-added low-resolution spectra of celestial objects, each spectrum combined from repeat exposure ofExpand


Peering through the OH forest: a new technique to remove residual sky features from Sloan Digital Sky Survey spectra
The Sloan Digital Sky Survey (SDSS) currently provides by far the largest homogeneous sample of intermediate signal-to-noise (S/N) ratio optical spectra of galaxies and quasars. The fully automatedExpand
The sky subtraction performance of multi-fiber spectrographs are discussed, analyzing in detail the case of the OPTOPUS system at the 3.6 meter ESO telescope at La Silla. A standard technique, basedExpand
Sky subtraction at the Poisson limit with fibre‐optic multiobject spectroscopy
We report on the limitations of sky-subtraction accuracy for long-duration fibre-optic multiobject spectroscopy of faint astronomical sources during long-duration exposures. We show that whileExpand
On-sky tests of sky-subtraction methods for fiber-fed spectrographs
We present preliminary results on on-sky test of sky subtraction methods for fiber-fed spectrograph. Using dedicated observation with FLAMES/VLT in I-band, we have tested the accuracy of the skyExpand

We introduce Zurich Atmosphere Purge (ZAP), an approach to sky subtraction based on principal component analysis (PCA) that we have developed for the Multi Unit Spectrographic Explorer (MUSE)Expand
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)
The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, also called the Guo Shou Jing Telescope) is a special reflecting Schmidt telescope. LAMOST’s special design allows both a largeExpand
The potential of night-sky emission lines recorded on every long-exposure astronomical spectrum, for wavelength calibration, is reemphasized. The previously published high-resolution atlas, based onExpand
Sky subtraction with fibres
The precision and reliability of sky subtraction is the limiting factor in faint-object spectroscopy. It has been believed that precise sky subtraction cannot be achived with multi-object fibreExpand

A new method based on the iterative subtraction of continuum estimates and eigenvector sky models derived from singular value decompositions of sky spectra andsky spectra residuals for estimating and removing the spectrum of the sky from deep spectroscopic observations is developed. Expand
The Vignetting Effect of a LAMOST-Type Schmidt Telescope
Optical vignetting of a Schmidt reflector is caused mainly by the spherical primary mirror not being big enough and by the effective light-collecting area of the corrector, which depends on theExpand
