OREKIT (ORbits Extrapolation KIT) is a low level space dynamics Java library. It provides basic elements (such as orbits, dates, attitude, and frames) and various algorithms to handle them (such as conversions, analytical and numerical propagation, and pointing).

ccurve_create.tcl is a TCL script (plus associated csh scripts) that makes it is possible to calculate cooling curves (plasma emissivities, in units of erg cm^3 s^-1) as a function of plasma temperature using the hot plasma codes available in the XSPEC spectral fitting program. Element-or-line-specific cooling functions can also be created. These can be used in hydrodynamical simulations to assess the total cooling rate, calculate the luminosity in a specific wavelength/energy range, or more generally to calculate X-ray or UV line diagnostics.

Oroboros is an astrology application. It is based on the Swiss Ephemeris (pyswisseph) for planetary calculations, the Olson timezone database (pytz) for date and time resolution, and the Qt4 toolkit (PyQt4) for the graphical user interface.

PAPFIP (Python And PGPLOT-based FITS Image Plotter) is a FITS image plotter based on the Python bindings to the pgplot graphics library. It is intended as a non-interactive (command line or script-driven) astronomical image plotter intended for the automated or repeated production of finalized publication-quality Postscipt files, rather than a method of inspecting or visualizing the data.

Hijra Islamic Calendar هجرة is an application for viewing the Islamic calendar (also known as Hijri calendar). It features a GUI with a tray applet. It includes both a high-level OOP library and a low-level library which can be used to implement other software that makes use of this type of calendar. It uses a special algorithm which gives much better precision than other known algorithms. It uses integer operations to avoid round off errors in floating point operations.

ZEBRA combines and extends several of the classical approaches to produce accurate photometric redshifts down to faint magnitudes. In particular, it uses the template-fitting approach to produce Maximum Likelihood and Bayesian redshift estimates.

Henry is an educational astrometry utility for performing calculations based on a Hertzsprung-Russel (H-R) diagram, such as spectroscopic parallax for working out the distance to a given star. Unlike many other solutions that use in-built images for their H-R diagrams, Henry plots data directly from the European Space Agency's HIPPARCOS catalog, allowing increased accuracy while also giving students greater room to experiment by exploring the catalogue themselves.
