ChiantiPy is a Python interface to the CHIANTI atomic database for astrophysical spectroscopy. The CHIANTI atomic database for astrophysical spectroscopy provides the information necessary to calculate the emission spectrum from hot plasmas. ChiantiPy provides several top-level classes to access the database and calculate continuum and emission line intensities.
I is a programming language that was designed to be efficient to write and run. The system incorporates many major libraries, allowing the creation of major projects such as Aciqra. It is an interpreted language and supports CGI scripting through the use of the CGI for Aciv/I extension.
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.
SAOImage DS9 is an astronomical imaging and data visualization application. DS9 supports FITS images and binary tables, multiple frame buffers, region manipulation, and many scale algorithms and colormaps. It provides for easy communication with external analysis tasks and is highly configurable and extensible. DS9 is a stand-alone application that requires no installation or support files. It supports advanced features such as multiple frame buffers, mosaic images, tiling, blinking, geometric markers, colormap manipulation, scaling, arbitrary zoom, rotation, pan, and a variety of coordinate systems.
TRIP is a general computer algebra system dedicated to celestial mechanics. It includes a numerical kernel and has interfaces to gnuplot and xmgrace. Computations can be performed with double, quadruple, or multi-precision. Users can dynamically load external libraries written in C, C++, or Fortran. Parallel computations on multivariate polynomials can be performed.
Open Source Astronomy is a comprehensive collection of astronomy software packages built for Linux, Mac OS X, and Windows. Each collection comprises approximately 5GB of software. An installation assistant is included along with a browsable documentation library covering all included packages.
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.
