VIE250808: Time series of ICRF3-sx defining sources

Solution description Time series of radio source coordinates of defining sources in ICRF3sx. For a description of the general setup of the VLBI solution, refer to Krasna et al. (2023) doi.org/10.1051/0004-6361/202245434 In vie250808 the session-wise datum is realized as: TRF: NNT/NNR for station coordinates w.r.t. ITRF2020-u2023 CRF: fixing of selected sources positions to ICRF3-sx with GA effect applied: with selected sources is meant the other ICRF3sx sources not included in vie250808a or vie250808b, respectively.

The position of sources provided in vie250808a and vie250808b soulutions are estimated without any constraints. Context We present the computation of global reference frames from very long baseline interferometry (VLBI) observations at the Vienna International VLBI Service for Geodesy and Astrometry (IVS) Analysis Center (VIE) in detail. Files description The columns in the provided files represent: col1: Modified Julian Date [day] col2: estimate of right ascension w.r.t.
