I've written a package for different astronomical and astrophysical purposes. The main web page is at http://conga.oan.es/~alonso/doku.php?id=jparsec
. They are a set of tools for astrophysical research in star formation and radioastronomy, developed in Java so that it can be used in any operating system. Main tools are SEDFit and DataCube, and a short description is included in the web page. The science section of my page contains a link to my thesis pdf with a detailed description (but in Spanish). Feel free to add it to your database if you find them useful.
