Celestial reference frame (CRF) from VIE2022 VLBI solution
收藏资源简介：
Celestial reference frame estimated from Very Long Baseline Interferometry (VLBI) technique measurements (1979.6 - 2023.0). VLBI global solution of S/X + VGOS 24h sessions. GENERATION TIME: 2023-07-28T02:41:15 DATA START: 1979-08-03T00:00:00 DATA END: 2022-12-30T00:00:00 ANALYSIS CENTER: VIE (TU Wien, Austria) CONTACT: VIE Analysis Center (vlbi_contact@tuwien.ac.at) SOFTWARE: VieVS v3.2 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.
