Galactic sky distribution of the fraction of sources that have 5p/6p astrometric solutions (i.e. have parallaxes and proper motions) for sources that also have dsc_classlabel=‘quasar’ (left) and dsc_classlabel=‘galaxy’ (right). The plot is shown at HEALPix level 7 (0.210 deg²) in a Hammer–Aitoff equal area projection with the Galactic centre in the middle, north up, and longitude increasing to the left. White indicates no sources.
