TECHNIQUE: VLBI
FREQUENCY BANDS: S/X + VGOS
FORMAT: ICRF
DESCRIPTION: CRF from the VLBI global solution S/X + VGOS, updated with additional VGOS sessions. Source positions are in the J2000 frame, but at the 2015.0 galactic aberration epoch. Reported source position errors are inflated with scaling factors: 1.5 RA, 1.5 De, and a RA/Dec noise floor 30/ 30 micro-arc-sec is applied.
