Source flux-density monitoring in the VGOS era

Paper in 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.
