Parameter Determination and Fe-Ar Calibration Spectrum Identification for the Coude Spectrograph-CCD System of the 1m Telescope at Yunnan Observatory

    Graphical Abstract
    • Abstract
  • Related parameters of the Coude spectrograph-CCD system and identifications of Fe-Ar emission spectra in the CCD corresponding region are given in this paper for the 1M telescope at Yunnan Observatory. It is found that the chromatic dispersion of the Coude system is almost flat. Dispersions in grade 1-3 are 8.391ű0.09Å/mm(m=1), 4.185ű0.05Å/mm(m=2) and 2.794ű0.03Å/mm(m=3) respectively. The identification chart of the Fe-Ar spectra contains standard emission line from 3370 to 11150Å. The wavelength table listed and the chards shown can be used for the wavelength calibration of program objects.
