Notes. Column 1 gives the HEALPix level considered (defining the spatial correction term), Col. 2 gives the weighted mean and error of the offset between the observed GEDR3 parallax and the photometric parallax, Col. 3 gives the weighted mean and error of the L20 correction, Cols. 4–7 give the weighted mean and error for the spatial correction, the magnitude correction, the total correction, and the offset between the corrected GEDR3 parallax in the present work (PW) and the photometric parallax. Column 8 gives the number of stars. The sample sizes of 66 and 54 stars are explained in Sect. 5.3.
This model results in a Δ(PZPO corrected parallax) of 0.00 ± 2.93 μas when using the L20 correction.
