ICRF3

The third realization of the International Celestial Reference Frame (Charlot et al. 2020, A&A 644, A159), adopted by the IAU as the fundamental celestial reference frame from 1 January 2019: VLBI positions of extragalactic radio sources at S/X, K and X/Ka bands. These are the paper's tables as published by CDS in VizieR catalogue J/A+A/644/A159, fetched from the VizieR mirror at China-VO. original/ holds the files and ReadMe as distributed, and data/ holds each table as Parquet, converted with astropy's CDS reader from the ReadMe's byte-by-byte description; the ReadMe's record counts are the reference for row counts.
