| Popis: |
We present results of amplitude calibration of the RadioAstron Space Radio Telescope (SRT) at wavelenghts of 1.35, 6.2,18, and 92 cm. Flux density calibrated internal noise signals and SEFDs are found to be stable within the errors at thelevel of 3–13%. We have used the flux density scale by Baars et al. (1977). The known issue of the variability of calibratorswas resolved performing comparison with two other flux density scales. We have resolved the issue by averaging SRT noisediode signals measured relative to Cassiopea A and Crab Nebula. |
