This is The South-Equatorial Galaxy Catalogue (SEGC), version 2.0, dated 
November 2019.  It differs from previous versions in the following ways:  

  1) The B1950.0 positions of the previous versions have been precessed to
     J2000.0.
  2) Diameters and axis ratios have been reduced to the B = 25.0 mag arcsec^-2^
     systems of RC3 for compatibility with other lists.
  3) V-band magnitudes and B-V colors from RC3; transformed from SDSS, ESO-LV,
     or 6dF data; or, occasionally from other sources, are listed.  
  4) Redshifts given as V = cz, are usually taken from 6dF.  Sources for the 
     photometry and redshifts are also listed.

The distribution includes five files:

    segc20.txt -- SEGC, version 2.0; diameters and axis ratios given as
      logD (D in units of 0.1 arcminutes) and logR (R = D/d).
    segc20am.txt -- SEGC, version 2.0am; major and minor diameters given in
      arcminutes.
    segc20.fmt -- a short example file for SEGC.
    segc20intro.txt -- This file.
    segc20doc.txt -- documentation for this release.

These files are 7-bit ASCII files.
