System Noise and Accuracy of Primary Flux Density Calibrators and Scales on RadioAstron Space Telescope Data

—We investigate the physical reason of the found difference in the flux density calibration for the space radio telescope on the “primary” calibrators Cassiopeia A and Crab Nebula. Twenty internal noise sources (or noise generators) of space radio telescope are analyzed as “secondary” standards meas...
