This catalog consists of galaxies from the 2MASS Redshift Survey (2MRS) that show radio emission in the images of NVSS or SUMSS. For typical low-power radio galaxies, such as Cen A or M87, the catalog is complete to a few hundred Mpc.
Stamps of the optical+radio emission have been gathered into in one big document (35 MB); they can also be viewed using the convenient HTML catalog:
2MASX Target name of the object from 2MRS database NED_id NED id of galaxy ra (deg) Right Ascension of galaxy dec (deg) Declination of galaxy l (deg) Galactic longitude b (deg) Galactic latitude Kmag (mag) K-band isophotal flux, AB magnitude, corrected for galactic extinction Kmag_err Uncertainty on K z Heliocentric redshift zdist Peculiar-velocity corrected redshift zdist_err Uncertainty on z_dist D (Mpc) Inverse-variance weighted mean of distance from NED-D and peculiar velocity corrected Hubble-distance D_err Uncertainty on the former row gal_type Galaxy morphological type code: -9 to 9, encodes Hubble sequence, 98 if galaxy has never been examined (Huchra et al. 2012, Table A8) n_nvss Number of radio Gaussians matched to galaxy (after manual inspection) n_sumss Number of radio Gaussians matched to galaxy (after manual inspection) F1400 (mJy) Sum of integrated flux at 1.4 GHz of all radio matches (zero if n_nvss=0) F1400_err Uncertainty on the former row F843 (mJy) Sum of integrated flux at 843 MHz of all radio matches (zeros if n_sumss=0) F843_err Uncertainty on the former row Fsyn (mJy) Synthetic flux at 1.1 GHz, obtained using alpha=-0.6 Lsyn (erg/s) nu L_nu at 1.1 GHz sum_ma (deg) Sum of deconvolved FWHM of the major axis of all matched radio Gaussians max_ma (deg) Largest deconvolved major axis FWHM of all matched radio sources lim_ma Limit flag on major axis (=0 if source is resolved) max_dist_to_gal (deg) Maximum distance between the galaxy and the radio matches min_dist_to_gal (deg) Minimum distance between the galaxy and the radio matches contour_dist (deg) Distance of the galaxy to the second-highest radio contour (zero if within contour) geo_cen_ra (deg) RA of the geometrical center geo_cen_dec (deg) Decl. of the geometrical center flux_cen_ra (deg) RA of the flux-weighted center flux_cen_dec (deg) Decl. of the flux-weighted center class Classification based on morphologyThe columns of the catalog with all matches:

We recommend using K3Match for this.
