Notes. Listed are only the 29 stars that need homogenization. Right ascension α_original and declination δ_original are coordinates from the original publications. The shifts in right ascension Δα and declination Δδ must be subtracted from the original coordinates α_original and δ_original to match the ICRF3 coordinates. The quantities σ_α,CRF and σ_δ,CRFι are the uncertainties of the calibrator coordinates in ICRF3, to be applied as uncertainties for the star coordinates. The last two columns list the resource where the coordinates most likely used in the original publication were found, which can be the VLBA observation archive (VLBA o. a.) or the original publication, and the reference of the original publication. ⁽¹⁾Not in ICRF3. The position used is from rfc_2018b. ⁽²⁾Correct position, obtained from correspondence with main author. ⁽³⁾The position used is from the ICRF3 K-band catalog. ⁽⁴⁾Publication directs to ICRF2, which was therefore used to get the original position.
