Noises in Observing Stellar Spectra Using Solid-State Detectors and Method to Reduce Them
Taking the No. 1 CCD system of Yunnan Observatory, attached to CCD-Coud'e spectrographic system, as an example, the noises induced by area (CCDS) or linear solid-stote detectors used for the spectra observations with large dispersion and the methods to reduce those noises, mainly the method for flatfielding are discussed.
