Optionally, the entire SED (spectral energy distribution) is sent to the user in a file.

Data Reduction Expert Assistant ( DRACO )

The use of large format detectors, increased access to very large astronomical databases, and other developments in observational astronomy have led to the situation where many astronomers are overwhelmed by the reduction and analysis process. Draco is a novel approach to data reduction and analysis which works in conjunction with existing analysis systems such as STSDAS/IRAF, IDL, etc. Draco takes on much of the mechanics of the process, allowing the astronomer to spend more time understanding the physical nature of the data.

Observations that require dark skies are obtained at Crni vrh observing station where two small automated telescopes equipped with state of the art systems for CCD photometry are located.

Astronomers run university courses of astronomy for astronomers as well as physicists and primary and secondary school teachers. The Observatory has a public astronomical library. Research is in large part done in collaboration with the Astronomical Observatory of Padua. Reseach interests include general relativity, active galactic nuclei, close stellar binary systems, pulsars, comets and telescope automation.

University of Washington - Department of Astronomy

The Department participates in these major projects: Apache Point Observatory, Sloan Digital Sky Survey and NASA High Performance Computing and Communications. The HPCC Project offers the results of simulations including gas dynamics or just dark matter. Their software exchange contains N-body codes, tools for particle based codes, the Theoretical Image Processing System, TIPSY, and Lecture notes for introductory astronomy courses.

WebStars ( Astrophysics on the Web )

WebStars, at NASA's High Energy Astrophysics Science Archive Research Center, is about astronomy & astrophysics; the Space Science Web Group; software & icons downloading; WWW technical pages & style guides; on-line articles about astronomy on the Web; HEASARC/StarTrax Browse and other online services; and virtual reality. If you have a document or resource you wish to be included, send me the text (preferably HTML) or a URL. WebStars is referenced by many other sites on the Web. It has been expanded and reorganised extensively since its first announcement in February, so visit again! The What's New page lists file change dates, to help you discover updates. Also, there are New Additions areas.

WIP

WIP is a simple to use command line user interface used to produce high quality graphical output. It is linked with the PGPLOT subroutine package providing easy interaction with those subroutines.

Xephem: An Interactive Ephemeris for X Windows/Motif ( XEPHEM )

Xephem is an interactive astronomical ephemeris program for X Windows systems. It computes heliocentric, geocentric and topocentric information for celestial objects. Xephem has built-in support for all planets; the moons of Jupiter, Saturn and Earth and Mars' central meridian longitude. Xephem supports objects in heliocentric or Earth orbit given the appropriate elements. Sample databases of over 16000 objects are included in the release kit. Xephem generates data in configurable tabular forms and in several detailed graphical formats. Xephem can plot and list all data fields and can be programmed to search for arbitrary circumstances. Xephem can serve as the control point for automated telescopes and can connect to auxiliary database servers in real-time via named streams pipes (UNIX fifos).
