NAME

       topcat - Tool for OPerations on Catalogues And Tables

SYNOPSIS

       topcat <flags> [[-f <format>] <table> ...]

DESCRIPTION

       TOPCAT  is  an  interactive  graphical  viewer  and editor for tabular data. Its aim is to
       provide most of the facilities that astronomers need  for  analysis  and  manipulation  of
       source  catalogues  and  other  tables, though it can be used for non-astronomical data as
       well. It understands a number of different  astronomically  important  formats  (including
       FITS and VOTable) and more formats can be added.
