CATALOG FORMAT

        In the Plateau de Bure format each  source  uses  one  line  of  the
    catalog  file.  Each  line  should  contain  the  following  consecutive
    keywords (some may be omitted):
     1) Source name field:
       The source name field is a composite item which can accomodate several
       names for a single source. Names should be separated by a vertical bar
       ( | ) with no embedded spaces, e.g.: B0415+379|3C111
       Each name must have at most 12 characters.
     2) Coordinate system: 2 characters, optional, may be:
          EQ for equatorial coordinates. If "EQ" is given explicitely,
                                 then the Epoch  keyword is mandatory.
          GA for Galactic II coordinates.
          EC for J2000 Ecliptic coordinates
          HO for horizontal coordinates
          DA for equatorial, present-day coordinates.
     3) Epoch:  needed for equatorial coordinates after "EQ" keyword.
     4) Longitude-like coordinate: in degrees, except for EQ and DA where it
        should be in hours. Format is like hh:mm:ss.sss or dd.ddd or hh:mm.mmm
     5) Latitude-like coordinate: in degrees, same format as above.
     6) Velocity type: alphabetic code , such as "LSR", "HELIO" or "EARTH".
     7) Velocity: in km/second, in the corresponding reference frame (LSR,
        Heliocentric, or EARTH=local). Default is zero.
     8) Intensity type: Either "FLUX" or "MAGNITUDE" (optional)
     9) Intensity: Either the Flux in Jansky or the magnitude (optional)
        The flux can be followed by a spectral index.
