XEPHEM is a very exact and user-friendly planetarium program for Unix machines. It provides access to the Digital Sky Survey, to the Guide Star Catalog, and to other astronomical catalogs (e.g., the Hipparcos catalog, GCVS, etc.). It is currently only installed on the OSF machines.
The following astronomical data-bases are currently installed at IAAT for use with xephem. Unless otherwise noted, the catalogs were obtained from ftp://iraf.noao.edu/contrib/xephem/catalogs/. For these catalogs, the information on the catalogs appearing below is modified from the README file on this FTP-Site and from information in the files. For catalogs obtained from other sources, the information has been written by the undersigned. If you are interested in the installation of any other catalogs, please email Jörn Wilms (email@example.com).
tle-new.edb contains the newest osculating elements of the 100 brightest satellites, converted from the Two-Line Elements as posted on the CelesTrak WWW (author T.S. Kelso firstname.lastname@example.org). Mirrored and converted to the xephem format weekly at IAAT.
tle-all.edb contains the newest osculating elements of about 8000 satellites posted by Mike McCant (email@example.com on his FTP-Site. Mirrored and converted to the xephem format weekly at IAAT.
comets.edb contains the osculating elements of currently visible comets as provided by the IAU Minor Planet Center on their Orbital Elements: Comets page. Mirrored and converted to xephem format weekly at IAAT.
bs.edb is the Bright Star catalog.
GCVS.edb is the General Catalog of Variable Stars.
ppm.xe is the Position in Proper Motion catalog in special compressed format (can be used as a catalog for background stars).
hipparcos.edb: The Hipparcos main catalog, as available from ESA. More Information on the Hipparcos satellite and catalog can be found at ESA's Hipparcos Home Page.
gsc: The IAAT CD-ROM of version 1.1 of the GSC has been converted such that it can be used as a catalog for field-stars (use right mouse button in the sky view window). To save bandwidth, please do not change the source for the GSC to an external source.
lbn.edb is Lynds' Catalog of Bright Nebulae, 1965.
ldn.edb is Lynds' Catalog of Dark Nebulae, 1962.
sh2.edb is the Sharpless catalog of HII regions, 1959.
NGC.edb is the NGC catalog.
IC.edb is the Index Catalog culled from the latest NASA-ADC server (many thanks to Christos Siopis, firstname.lastname@example.org). All NGC objects have been removed.
UGC.edb is the Uppsala General Catalog extracted from RC3, the Third Reference Catalog of Bright Galaxies, available from ftp://adc.gsfc.nasa.gov/pub/adc/archives/catalogs/7/7155. N.B. magnitudes for which no entry existed in the RC3 have been set to 10.99.
cgcg.edb is CGCG (Galaxies and Clusters of Galaxies) Catalog Converted from CGCG Catalog on the CD-ROM from the Astronomical Data Center "Selected Astronomical Catalogs" by Matthias Cramer (email@example.com).
qso.edb is from "Quasars and Active Galactic Nuclei (7th Ed.)", Veron-Cetty M.-P., Veron P. ESO Scientific Report 17 (1996).
Abell.edb contains the Catalog of Rich Clusters of Galaxies (Abell G.O., Corwin Jr. H.G., Olowin R.P., 1989, Astrophys. J. Suppl. Ser. 70, 1). The magnitude given is for the 10th brightest cluster galaxy, the size has been set arbitrarily to 100 arc seconds.
pulsars.edb is a converted version of the Princeton Pulsar Catalog (J. H. Taylor, R. N. Manchester, and A. G. Lyne 1993, ApJS. 88, 529). According to the documentation in the file, the magnitude has been computed from the following C-expression:
