CENSORS: A Combined EIS-NVSS Survey of Radio Sources - II. Infrared imaging and the K-z relation.
BROOKES M.H., BEST P.N., RENGELINK R. and ROETTGERING H.J.A.
Abstract (from CDS):
In conjunction with spectroscopic observations, the K-band magnitudes have been aperture corrected and used to establish a K-z relation for the CENSORS radio galaxies. This relation is of interest because of its variation, at z > 1, between radio surveys of different flux-density limit. Establishing this relation for CENSORS may shed light on the origin of this variation and will allow an appropriate K-z redshift estimator for any CENSORS source which remains without a spectroscopic redshift. It is shown that whilst the K-z relation for CENSORS is fainter than that of 3CRR at all redshifts, it agrees well with that of 7C over all redshifts studied.
