Sky plot of ERCSC sources in galactic coordinates. Black filled hexagons are ERCSC point-sources and blue filled hexagons are ERCSC sources flagged as extended. Red hexagons are sources associated with IIFSCz IRAS FSC galaxies, after scrutinising suspect categories with NED (and excluding some, as described in the text). Green hexagons are ERCSC sources not associated with IIFSCz, but associated with bright galaxies in NED (only for | b | > 60° for extended sources).
