Summary:
C: Tool for OPerations on Catalogues And Tables
Description:
C: >-
<p>
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. It is especially good at
interactive exploration of large (multi-million row, lots of
columns) tables.
</p>
<p>
It offers a variety of ways to view and analyse tables,
including a browser for the cell data themselves, viewers for
information about table and column metadata, and facilities for
sophisticated interactive 1-, 2-, 3- and higher-dimensional
visualisation, calculating statistics and joining tables using
flexible matching algorithms. Using a powerful and extensible
Java-based expression language new columns can be defined and
row subsets selected for separate analysis. Table data and
metadata can be edited and the resulting modified table can be
written out in a wide range of output formats.
</p>
<p>
It is a stand-alone application which works quite happily with
no network connection. However, because it uses Virtual
Observatory (VO) standards, it can cooperate smoothly with other
tools, services and datasets in the VO world and beyond.
