Addded TOPCAT to data analysis tools
20 November 2012 - Filed in: data analysis
I’ve added [TOPCAT](http://www.star.bris.ac.uk/~mbt/topcat/) to the list of data analysis tools.
>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 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 1-, 2-, 3- and higher-dimensional visualisation, calculating statistics and joining tables using flexible matching algorithms
I also noticed that Venuz has been updated
[Veusz](http://home.gna.org/veusz/) is a GUI scientific plotting and graphing package written in Python. It is designed to produce publication-ready Postscript or PDF output. SVG, EMF and bitmap export formats are also supported. The program runs under Unix/Linux, Windows or Mac OS X, and binaries are provided. Data can be read from text, CSV or FITS files, and data can be manipulated or examined from within the application
