VStar is a multi-platform, easy-to-use variable star observation visualisation and analysis tool. Data can be read from a file or the AAVSO database, light curves and phase plots created, period analysis performed, and filters applied. Plugins can be developed, e.g. to make additional observation sources available.

XmgFit is a wrapper for Xmgrace (*) allowing to use comfortable the non-linear curve fitting capability of Xmgrace from the command line. Therefore the capabilities are limited by xmgrace. Please refer to the xmgrace users guide for more details. It is also handy to incorporate in shell scripts. The -s or --scripty option returns all result values xmgrace provide in an EVALuable format to make them easy available in shell scripts. *) http://plasma-gate.weizmann.ac.il/Grace/

The Gauss–Newton algorithm is realized in NI LabVIEW 8.6. The program finds parameters of the chosen function as well as their corresponding uncertainties. It is used for educational purposes at undergraduate level.
