AIPS++ (Astronomical Information Processing System)

AIPS++ is a software package which will calibrate and image (primarily) radio astronomical data. It is being written in an object-oriented style using the C++ language. AIPS++ is being developed by an international consortium. AIPS++ is not yet of interest to users, although there are some email reflectors you may wish to join for information. A beta library release is available via anonymous ftp. This may be of interest to C++ software developers.

Molonglo Observatory Synthesis Telescope (MOST)

The MOST consists of two cylindrical paraboloids, 778m x 12m, separated by 15m and aligned East-West. A line feed system of 7744 circular dipoles collects the signal and feeds 176 preamplifiers and 88 IF amplifiers. The telescope is steered by mechanical rotation of the cylindrical paraboloids about their long axis, and by phasing the feed elements along the arms. The resulting `alt-alt' system can follow a field for +/- 6 hours (necessary for a complete synthesis with an East-West array) only if the field is south of declination -30 degrees. For fields near this limit the signal-to-noise ratio is considerably lower for the first and last hour or so due to the lower gain of the system at large `meridian distance' angles.

Torun Radio Astronomy Observatory (TRAO)

Torun Radio Astronomy Observatory (TRAO), now part of Torun Centre for Astronomy is an educational and research facility of the Nicolaus Copernicus University, Faculty of Astronomy and Physics, Torun, Poland. The Observatory main instrument is 32m modern design radio telescope usable up to 50 GHz. Presently equipped with cooled receivers for L and C bands is used extensively for VLBI, pulsar timing and spectroscopy. Since April 1998 Torun is the full member of the EVN.

UTR-2 catalogue

The very-low frequency sky survey of discrete sources has been obtained in the Institute of Radio Astronomy of the Ukrainian National Academy of Sciences (Kharkov, Ukraine) with the UTR-2 radio telescope at a number of the lowest frequencies used in contemporary radio astronomy within the range from 10 to 25 MHz.

VLBI Space Observatory Programme (VSOP)

The VSOP (VLBI Space Observatory Programme) mission is led by the Institute of Space and Astronautical Science, in collaboration with the National Astronomical Observatory of Japan. The first VSOP satellite was successfully launched 12 February 1997 on the new ISAS M-V rocket from the Kagoshima Space Center. The satellite, renamed HALCA after its successful launch, sucessfully deployed an 8 meter diameter radio telescope in orbit on 27 & 28 February 1997. HALCA is in an elliptical Earth orbit, with an apogee height of 21,000km and a perigee height of 560km, which enables VLBI (Very Long Baseline Interferometry) observations on baselines up to three times longer than those acheivable on Earth.

Ventspils International Radioastronomy Centre (VIRAC)

The Ventspils 32-m antenna is the biggest in the Baltics. The main purpose of the VIRAC is to take part in observations at high angular resolution of faint sources of cosmic natural and artificial radiation in order to accumulate observational data for fundamental and practical research programmes in radioastronomy, astrophysics, cosmology, geophysics, geodynamics, geodesy, co-ordinate-time service and other.

Very Small Array (VSA)

The Very Small Array is an interferometer array designed to make images of the cosmic microwave background (CMB) radiation on angular scales around one degree. The VSA consists of an array of 14 small antennas, working at a frequency in the range 26-36 GHz, and will be sited at the Teide Observatory in Tenerife.

Westerbork Synthesis Radio Telescope (WSRT - NFRA)

The Westerbork Synthesis Radio Telescope is a linear 3 kilometer array located near the village of Westerbork in the North-East of the Netherlands. The WSRT consists of fourteen 25m dishes along a perfect east-west line. By combining these fourteen elements one can synthesize a radio telescope with a diameter of 3 kilometers.

Westerbork Synthesis Radio Telescope (WSRT) observations archive (NFRA, Dwingeloo)

A query form lets you search the catalogue of all observations done with the WSRT since the beginning of its operations in 1970. Searches are possible by equatorial or galactic coordinates, by source name and some other parameters. Requests for data from the archive may be submitted after selection.

Zurich Solar Radio Spectrometer

The Radio Astronomy Group (RAG) of ETH in Zurich, Switzerland, recorded solar radio spectrograms with an analog spectrometer called Daedalus (1974-1993) in the range of 100-1000 MHz. Its observation list can be accessed directly. Two digital spectrometers, Ikarus (1978--1985) and PHOENIX (1988--1994), cover a range from 100--1000 MHz and 0.1--3 GHz, respectively. And since 1998 the new and improved Phoenix-2 Spectrometer covers a range from 0.1 -4 GHz. These data can be accessed by the ASPECTimage retrieval system. Their observation list contains references to frequency programs that indicate which frequencies were observed. More information can be obtained from RAG members.
