Astro::Aladin is a an object-oriented interface into the resources provided by the CDS Aladin project. The Aladin Java application is driven in script mode using an anonymous pipe, while high level access to resources is provided by the module which disguises the mechanics of the data access.
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.
FTOOLS is a highly modular collection of over 200 utilities for processing and analyzing data in the FITS (Flexible Image Transport System) format. Each utility performs a single simple task such as the presentation of file contents, extraction of specific rows or columns, appending or merging tables, binning values in a column, or selecting subsets of rows based on a boolean expression. It provides both generic processing and analysis utilities and utilities specific to high energy astrophysics data sets used for the ASCA, EINSTEIN, ROSAT, GRO, VELA5B and XTE missions.
Simulum deals with different simulations of star movements and their visualizations. At first it looks at the projection and accumulation of star brightness. In actually doing this it distributes stars among a three dimensional figure. To get a nice effect it combines the photographic image production with a moving view point. So the outcome is the visual impression of flying through a star field. Secondly it studies different algorithms of particle movements and clustering. The primary approach uses a combination of Newton's gravitational law, energy, and impulse conservation. At all these stages an highly dynamic view of the processes is able to be produced.
Squeuer is a queueing proxy for Seti@Home. It keeps a configurable sized queue of work units so that the client will always be able to get a new work unit immediately upon finishing one. It queues results for uploading should the main Seti@Home site be overloaded or down. Results are never lost and the client is never delayed waiting to upload a result. It can handle multiple users running the Seti@Home client on multiple machines all connecting to Squeuer. It has been tested and found to work on different versions of Unix, MacOS, and Windows. All it requires is a Perl 5 interpreter.
skyviewer is an OpenGL-based program to display HEALPix-based skymaps, saved in FITS format files. The loaded skymaps can be viewed either on a 3D sphere or as a Mollweide projection. In either case, realtime panning and zooming are supported, along with rotations for the 3D sphere view, assuming you have a strong enough graphics card.
