J/AJ/80/771 J/AJ/80/771 5-GHz Survey of Bright Galaxies R Sramek Astron. J. 80 771 1975 1975AJ.....80..771S VII/16 : Reference Cat. of Bright Galaxies (1st Ed.) (de Vaucouleurs+ 1964) VII/112 : RC2 Catalogue (de Vaucouleurs+ 1976) VII/155 : Third Reference Cat. of Bright Galaxies (RC3) (de Vaucouleurs+ 1991) Galaxy catalogs Radio continuum The 1135 galaxies in the Reference Catalogue of Bright Galaxies (Cat. <VII/16>) with declinations between +10{deg} and +70{deg} were surveyed at 6-cm wavelength with a 3-sigma detection limit of about 30mf.u.; of these 149 were detected. For 90 of these galaxies, spectral indices were obtained. There is a suggestion that the elliptical galaxies have flat spectra more often than the spiral galaxies.

Galaxy Galaxy name number=1 N prefix denotes an NGC (See Cat. <VII/118/>) galaxy, I is an IC (See Cat. <VII/118/>) galaxy, an A an anonymous galaxy. --- l_F5GHz lower limit flag --- F5GHz Final flux density at 5GHz mJy e_F5GHz rms uncertainty on F5GHz mJy n_F5GHz Notes on F5GHz number=2 P: possible detection; the flux density measured with the 300ft was less than twice the error of the 140ft flux and, therefore, the detection was considered unconfirmed PC: this is only a possible detection since there was a confusing source nearby R: the flux measured with the 140ft was greater than 1.6 times the flux from the 300ft and the difference exceeds the range of the errors of the two measurements. These sources are probably resolved with the 300ft beam or they have a complex structure. The flux density given is the 140ft measurement and the errors may be larger than indicated. O: the source is offset from the galaxy position. The amount and direction of this offset is mentioned in the Notes column. --- Note N: note detailed in file "notes.dat" --- Diam Note on the diameter number=3 D: the optical diameter from the RCBG (Cat. <VII/16/>) is greater than 6 arcmin; the radio source is not necessarily resolved, but the flux densities of these large galaxies should be used with caution. --- l_SI Limit flag on SI --- SI Spectral index of the source number=4 The spectral index is defined here as flux ~ {nu}^{alpha} --- Ref References for a second flux-density measurement number=5 References for flux densities used in determining the spectral indices A: Dwingeloo Survey (Dixon, 1970, Cat. <VII/2>) B: Ohio Survey (Dixon, 1970, Cat. <VII/2>) C: De Jong (1967ApJ...150....1D) D: De La Beaujardiere et al.
