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.
Remote Telescope System (RTS2) is an integrated system for remote observatory control. It is designed to keep an observatory running, protect it from elements, take images, ensure that pointing is good, react to TOOs, keep track of what was done, send you data, and help you to do science. It picks targets from a database table, stores image meta-data in a database, processes images, and stores WCS coordinates in the database. An abstract device layer enables control of all possible combinations of mounts, CCDs, photometers, and roof and cupola controllers.
Astro::DSS Module is an object orientated Perl module that provides an interface to both the first and second Digital Sky Surveys at the ESO-ECF online archive. While the first sky survey is 100% complete, the second survey covers 98% of the sky in Red, 45% of the sky in Blue, and 27% of the sky in Infra-red.
TerraJ is a Java port of fractal terrain and simulated solar system generation programs. The porting has included extensive refactoring, the creation of a documented API to enable reuse of parts in other programs, and extensions such as new Swing user interfaces. Full javadoc for the classes in the project is available.
