AstroBuffer is a CCD astrophotography image manipulation application. It can open FITS and SBIG (st9) files. Contrast is adjustable to view different backgrounds and ranges of an image. It can scale, shift, rotate, and zoom in and out. Images can be aligned based on two star alignment, and can be summed, subtracted, averaged, and divided. RGB color images can be created from three images. Images can be saved as FITS or as any format that QT supports.

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.

Extrema, originally developed in the fields of nuclear and particle physics, is a powerful visualization and data analysis tool that enables researchers to quickly distill their large, complex data sets into meaningful information. Its flexibility, sophistication, and power allow you to easily develop your own commands and create highly customized graphs.

StarPlot is a GTK-based program, written in C++, which can be used interactively to view three-dimensional perspective charts of stars. Charts can be recentered, rotated, or zoomed in or out with a mouse click (this can also, of course, be done via dialog boxes for more precision). Stars may be viewed (or ignored) by spectral class and absolute magnitude. Other features include support for both celestial and galactic coordinate systems, the ability to display extended non-stellar objects, and a pop-up Hertzsprung-Russell diagram. StarPlot is also packaged with starconvert, a utility which converts line-oriented stellar data records to StarPlot format. Most star data files available on the Internet can be converted this way if a short file describing the original file format is provided to starconvert.

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.

SkyDome is a tool to demonstrate the location of stars, planets, constellations, and the Milky Way during Earth's rotation. Besides the optical view, various other star maps are incorporated from satellites like COBE, EGRET, and IUE, making the multi-wavelength Milky Way visible to the user.

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.

Vit 1.00

SAOTrace is a suite of software designed to simulate the as-built performance of grazing-angle X-ray optics using the ray-tracing approach. It is derived from portions of the NASA OSAC (Optical Surface Analysis Code) software suite. It can model nested conical as well as flat optical designs, and includes the ability to model arbitrary support structures and baffles. It can model non-ideal multi-layer reflective coatings as well as scattering from the optical surfaces.
