A celestial reference frame derived from observations with the Very Long Baseline Interferometry Global Observing System
Aims: We computed a celestial reference frame (CRF) from Very Long Baseline Interferometry (VLBI) Global Observing System (VGOS) data after five years of regular observations (155 multi-baseline 24-hour VGOS sessions until 2024.0). In this paper we document the source selection and scheduling strategies for the individual sessions, and investigate the …
