Abstract:

    The   brightest extragalactic radio sources at 2.7 GHz are catalogued.
    The   complete  sample  comprises  233  sources  found  in  the  major
    centimeter   wavelength   surveys   carried   out   at   ANRAO/Parkes,
    NNRAO/Greenbank,  and MPIfR/Bonn:  the  sample covers 9.81  sr and has
    limits S(27) = 2.0 Jy and |b| > 10{deg}.  A critical reanalysis of the
    data shows that 227 (97 percent)  have optical identifications and 171
    (73  percent)  have  measured  redshifts.   The  implications  of  the
    catalogue   statistics  for  the  luminosity  functions  of  different
    radio-source populations are considered.

Note (1):  The 'IAUname' column gives the name of the source in IAU
          convention. The 'Name' column gives an alternative name, if
          available.

Note (2): These columns give the B1950 right ascension and declination of
          the source. Positions are from the first reference listed in the
          "r_RAh" column, and are optical positions with the following
          exceptions: if the optical position was of low accuracy and the
          source was compact, the radio position was used.

Note (3): This column gives the positional error. The quoted error is the
          rms in one direction in arcsec.

Note (4): This column gives the flux density at 2.7 GHz, in Jy. The 2.7 GHz
          flux-density scale was changed from that used by Kellermann et
          al. (1969ApJ...157....1K) to the Parkes flux-density scale.

Note (5): This column gives the spectral index between 2.7 and 5 GHz, in
          the sense of S {prop.to} {nu}^-{alpha}^.

Note (6): This column gives the optical classification of the source, as
          follows:

          Q   QSO confirmed by spectrum or variability (and including BL Lac
               objects).
          Q?  Stellar object on position.
          G   Galaxy confirmed by extended image.
          G?  Very faint object; presumed galaxy.
          EF  Empty field

Note (7): These columns give the redshift and redshift flag. The f_z
          column is marked with an asterisk ('*') if the redshift is an
          estimate.

Note (8): References to the given position are as follows: A '???' indicates
          that the entries in that column are not complete. The author
          intends to go back and fill in the missing info in the future.
