Notes.

^(a)

An additional uncertainty of 0.9 mas in right ascension due to the global astrometry errors on the phase-reference source position should be included when considering this position in the ICRF.

^(b)

The phase-reference source has an additional uncertainty of 1.4 mas in declination in the ICRF.
