Source flux-density monitoring in the VGOS era

Paper i proceeding, 2021

Source flux density is used to prepare optimal schedules of geodetic VLBI experiments in scheduling software packages such as Sked and VieSched++. It enters in the determination of the scan length to reach the signal-to-noise target to ensure successful radio-source detection. We present a comparison of different available catalogs and summarize the main current issues. We also present the first preliminary results of short-baseline (75 m) VGOS flux-density monitoring carried out in early 2021 using the Onsala Twin Telescopes.
