OTT quasar flux monitoring and amplitude calibration stability


  • Dr. Eskil VARENIUS

Primary authors


I will present results from a recent campaign to measure quasar flux densities using the single ONSA13SW (Ow) and ONSA13NE (Oe) 75m baseline. During 2021 we conducted more than 60 short (20m) experiments in order to measure flux densities of a few bright sources. The aims were to a) check and monitor the Oe and Ow RF stability in the long and short term, b) assess the feasibility of doing regular flux monitoring using this single baseline, and c) verify recent DBBC3 multicast amplitude calibration features added to the VLBI Field-system version 10.
