Some Problems on the Spectral Observation Made with the CCD System
During the spectral observation made with the CCD system on the camera(f=1900mm) of the Coude' spectrograph attached to the 1-m telescope at the Yunnan Observatory, the selection and the calculation of some important parameters, such as the wavelength photographed once, the dispersion, the rotation angle of the grating and the filters, etc., and some problems for attention arc presented in this paper.
