Notes. Column 1 gives the name of the catalogue. Columns 2–4 and 5–7 present the results for sources located at |b| ⩽ 20° and |b| > 20°, respectively. Columns 2 and 5 show the weighted mean of the offset between the observed GDR3 parallaxes and parallaxes from other surveys or methods. Columns 3 and 6 give the weighted mean of the L21 correction. Columns 4 and 7 indicate the number of sources with five-parameter solutions.
