Uncertainty of line-of-sight velocity measurement of faint stars from low and medium resolution optical spectra
László Dobos, Alexander S. Szalay, Tamás Budavári +3
Massively multiplexed spectrographs will soon gather large statistical samples of stellar spectra. The accurate estimation of uncertainties on derived parameters, such as line-of-s…
