Time series of radio source coordinates of defining sources in ICRF3sx.
Computed by Hana Krasna, TU Wien.

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.

The columns in the provided files represent:
col1: Modified Julian Date [day]   
col2: estimate of right ascension w.r.t. ICRF3-sx [mas]   
col3: formal error of the estimated right ascension [mas]     
col4: estimate of declination w.r.t. ICRF3-sx [mas]    
col5: formal error of the estimated declination [mas]  
col6: estimate of right ascension multiplicated with cosinus declination w.r.t. ICRF3-sx [mas]   
col7: formal error of the estimated right ascension multiplicated with cosinus declination [mas]   
col8: number of observations of the source in this session   
col9: name of the VLBI database
