The Astrographic Catalogue (AC) was an international effort designed to photograph and measure the positions of all stars brighter than magnitude 11.0. In total, over 4.6 million stars were observed, many as faint as 13th magnitude. This project was started over 100 years ago. The sky was divided among 20 observatories, by declination zones. Each observatory exposed and measured the plates of its zone, subsequently publishing the plate measures.
The U.S. Naval Observatory has completed data entry of the printed volumes of the AC, has completed the data reduction of each zone, and has converted the positions to the system defined by Hipparcos. The resulting catalog, called AC 2000, is now available.

Astronomical Software & Documentation Service ( ASDS )

The Astronomical Software and Documentation Service (ASDS) is a network service that allows you to find existing astronomical resources for solving your problem. ASDS started life as the Astronomical Software and Documentation Service, devoted entirely to astronomical software packages and their associated on-line documentation. Much code is rewritten these days, not because anyone has found a fundamentally better way to solve the problem, but because they simply don't know who has already done it, whether the code runs on the system they have available, or where to get it if it does. That is the problem that ASDS was intended to solve. The objectives of ASDS changed in 1998 when its scope was expanded to include astronomical observing sites and their associated telescope and instrument manuals, taken from a listing maintained by Liz Bryson (bryson@cfht.hawaii.edu). The service was renamed at this point.

Atomic Line List

The atomic line list is a compilation of approximately 855,000 allowed, intercombination and forbidden atomic transitions with wavelengths in the range from 0.5 Å to 1000 µm. Its primary intention is to allow the identification of observed atomic absorption or emission features. The list is nearly complete for all ionization stages of all elements up to zinc. Transition probabilities are available for nearly 14% of the lines; they are mostly derived from Opacity Project data.

Auckland Observatory and Stardome Planetarium

Situated in New Zealand's largest city. A public Observatory established in 1967. Now with a new (1997) 11 metre Zeiss planetarium.
Research interests include photometry of binary and variable stars.


Stellar coronae; EUV and X-ray observations. Member of the PSI Stellar Group; participation in XMM Cal/PV/GT Programs.

Austin Astronomical Society ( AAS )

Austin Astronomical Society (AAS) is a non-profit organization for anyone interested in any aspect of astronomy or the space sciences. A major portion of AAS activities are public education outreach efforts.

Australia Telescope Compact Array, Parkes, MOPRA - Schedules ( ATNF )

Observing Schedules for all ATNF Telescopes.

Australia Telescope National Facility - Positions vacant ( ATNF, CSIRO )

Australia Telescope National Facility - Preprints ( CSIRO - ATNF )

Current preprints from the Australia Telescope National Facility.

Australian Defence Force Academy - Astronomy ( ADFA )

Astronomy and Astrophysics Research Group of the School of Physics, University College, Australian Defence Force Academy, The University of New South Wales. Containing information on research interests and personnel.

Australian Journal of Physics ( AJP )

The Australian Journal of Physics publishes new and significant research in all fields of physics, ranging from elementary particles to astrophysics.

Australian National University - Relativity Group

Automated Patrol Telescope ( APT )

The Automated Patrol Telescope (APT) is a wide-field CCD imaging telescope, which is operated by the University of New South Wales at Siding Spring Observatory, Australia.

Automated Plate Scanner ( APS, Univ. Minnesota )

The APS Catalog of the POSS I contains millions of entries for stars and galaxies, and the corresponding Image Database contains their pixels and more. The data behind the Object Catalog and Image Database are generated from digitized Palomar Observatory Sky Survey plates. Object Catalog entries include calibrated magnitudes in two colors, positions to 0.2 arcseconds, confidence measures on neural network image classifications, colors, and various other useful parameters.

AVHRR Land Pathfinder Data Set ( AVHRR )

The Pathfinder AVHRR Land data sets are global, multichannel, land surface data derived from the Advanced Very High Resolution Radiometers (AVHRR) on the NOAA/TIROS operational meteorological satellites (NOAA-7, -9, and -11) which provide a continuous daily and composite data set from July 1981 through the present. These data, when complete, will enable studies of global vegetation and surface characteristics over more than a decade. Every effort has been made to provide a consistently processed data record by cross-calibrating instruments and minimizing changes to the processing algorithm during the processing of the 1981 to present data.
