VIII/64       Westerhout's Catalogue of 82 Discrete Sources   (Westerhout 1958)

A Survey of the Continuous Radiation from the Galactic System at a Frequency of 1390 Mc/s. Westerhout G. <Bull. Astron. Inst. Netherlands, 14, 215 (1958)> =1958BAN....14..215W
ADC_Keywords: Nonstellar objects; Radio sources Keywords: Radio sources - Nonstellar objects - Westerhout's objects Description: This catalogue was created based on the original published catalogue in the article by Westerhout G., 1958, Bull. Astron. Inst. Netherlands, vol.14, p.215, "A Survey of the Continuous Radiation from the Galactic System at a Frequency of 1390 Mc/s." His article describes the results of a survey of the radiation along the galactic ridge and a search for discrete sources. The observations were made with the 25-m radio telescope at Dwingeloo, which has a beamwidth of 0.57 degree at a frequency of 1390 Mc/s. The catalogue contains positions of 82 discrete sources. The epoch for positions in the original published catalogue was 1957.0. Positions referred to 2000.0 are shown in this machine-readable catalogue. File Summary:

Note on W: W 82 : This source number is listed but no position is given for it in the original Westerhout's catalogue. Thus, it is neglected in this machine- readable catalogue. Note on m_W: m_W describes distinguishable sources which are included in some of Westerhout's objects. See "notes.dat" file.

Historical Notes: * 15-Sep-1999: This catalogue was created by Junko Takahashi and Masatoshi Ohishi at the Astronomical Data Analysis Center, National Astronomical Observatory of Japan, based on the original published catalogue by Westerhout G., 1958, Bull. Astron. Inst. Netherlands, vol.14, p.215, "A Survey of the Continuous Radiation from the Galactic System at a Frequency of 1390 Mc/s." * 3-Nov-1999: Supplemental data about distinguishable sources which are included in the original Westerhout's objects were added. * 22-Feb-2000: "ReadMe" file is rewritten, and "notes" file is created by K.Nakajima. Acknowledgments: Takahashi and Ohishi are grateful to Dr. Mitsuru Soma for his codes for the coordinate conversion. They also wish to thank all members at the Astronomical Data Center, National Astronomical Observatory of Japan for their cooperation.
