The Use of a Standard Source of Synchrotron Radiation for Calibration of the Sensitivity of a Telescope with CCD Array and High Angular Resolution

A method involving the use of a primary standard source of synchrotron radiation for precision calibration of the sensitivity of telescopes equipped with a CCD array and high angular resolution is considered. The method is based on precision reproduction of the spectral energy characteristics, the Gaussian distribution of the spectral density of the irradiance over a radiating region, and the stability and reproducibility of the characteristics of synchrotron radiation in a single-electron regime.
