Aciqra is a night sky simulator to show the sky and celestial objects. It uses the highly precise Aloac program to calculate highly accurate positions for planets, stars, comets, and everything else in the sky for thousands of years into the future. It can load a variety of catalogs and even custom ones with a bit of extension.
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.
MultiSeti is a utility for the Seti@Home client which helps you manage multiple SETI packets. If you have dial-up access to the Net, want to download more than one packet, and don't want to run clients simultaneously, MultiSeti will run one after another (when one is finished analyzing, it starts seti to analyze the next packet).
McIDAS-Lite is a freely available demo for the full McIDAS software. It will connect to a variety of free online data sources for satellite data and display the images in a viewing window. Images can be looped and analyzed, and graphics overlays can be created to show maps and other geographical features. It is available for AIX, HP-UX, Irix, Linux, Mac OS X, Solaris Sparc, Solaris x86, and Windows XP with SFU.
NOVAS (Naval Observatory Vector Astrometry Subroutines) is an integrated package of subroutines for the computation of a wide variety of common astrometric quantities and transformations. It can provide the instantaneous coordinates (apparent, topocentric, or astrometric place) of any star or planet, and also provides general astrometric utility transformations, such as those for precession, nutation, aberration, parallax, etc. It is useful for data reduction programs, telescope control systems, and simulations.
