7C-III Sample

 

Here we give K-band photometry for narrow-lined radio galaxies at z>1.2 in this sample as presented by Lacy, Bunker & Ridgway (2001). Note that these authors present data on more objects than are included here. The K magnitudes for 7C1742+634 and 7C1751+680 were estimated from the H magnitudes presented in this paper assuming H-K=0.9. We also give the K-magnitudes after aperture correction to a fixed metric aperture and after emission line contribution correction as described and used in Jarvis et al. (2001) and Willott et al. (2003).

Col. 1 is the name of the source.
Col. 2 is the redshift.
Col. 3 is log10 radio luminosity at 151 MHz in units of W/Hz/sr. Calculated assuming a cosmology with Omega_M=0.3, Omega_Lambda=0.7, H= 70 km/s/Mpc.
Col. 4 is the measured K-band magnitude (Vega sysytem).
Col. 5 is the size of aperture (in arcsec) used for photometry
Col. 6 is the K-band magnitude after correction to a fixed metric aperture of size 64 kpc.
Col. 7 is the K-band magnitude after both aperture and emission line corrections.
