Probabililty to find a calibrator

Probability to find a calibrator source within a disk with a given radius in an arbitrary direction on the sky in the declination zone [-20, +90]

Red -- probability to find a source in the combined list of geodetic sources and VCS catalogues.
Blue -- probability to find a source in the list of geodetic sources only.
