Morphology-color diagram for 658 UKIDSSDR11PLUS sources with J < 19.5 and K < 19.5 in the 24 square arcmin field around VLSS J2217.5+5943. The color index J − K is computed from the Petrosian magnitudes. Black and red symbols indicate sources classified as star-like or as galaxies, respectively. The dashed lines mark the selection area for the galaxies in the present study.
