The Richardson-Lucy Deconvolution method to Extract LAMOST 1D Spectra
Min Li, Guangwei Li, Ke Lv +3
We use the Richardson-Lucy deconvolution algorithm to extract one dimensional (1D) spectra from LAMOST spectrum images. Compared with other deconvolution algorithms, this algorithm…
Cosmic Ray Removal in Fiber Spectroscopic Image
Zhongrui Bai, Haotong Zhang, Hailong Yuan +4
Single-exposure spectra in large spectral surveys are valuable for time domain studies such as stellar variability, but there is no available method to eliminate cosmic rays for si…
FGK 22 m Excess Stars in LAMOST DR2 Stellar Catalog
Chao-Jian Wu, Hong Wu, Kang Liu +8
Since the release of LAMOST (the Large Sky Area Multi-Object Fiber Spectroscopic Telescope) catalog, we have the opportunity to use the LAMOST DR2 stellar catalog and \emph{WISE Al…
A Practical Deconvolution Computation Algorithm to Extract 1D Spectra from 2D Images of Optical Fiber Spectroscopy
Guangwei Li, Haotong Zhang, Zhongrui Bai
Bolton and Schlegel presented a promising deconvolution method to extract 1D spectra from a 2D optical fiber spectral CCD image. The method could eliminate the PSF difference betwe…
Estimation of distances to stars with stellar parameters from LAMOST
Jeffrey L. Carlin, Chao Liu, Heidi Jo Newberg +15
We present a method to estimate distances to stars with spectroscopically derived stellar parameters. The technique is a Bayesian approach with likelihood estimated via comparison…
