J/AZh/72/12    Spectroscopy of Sources from 87GB Catalog    (Mingaliev+, 1995)

Spectroscopic Study of a Sample of Radio Sources from the 87GB Catalog Mingaliev M., Khabrakhmanov A. <Astron. Zh. 72, 12 (1995)> =1995AZh....72...12M
ADC_Keywords: Radio sources Description: A sample of 112 sources with flux densities higher than 200mJy at the 4.85GHz and with the range of declinations from +3 till +5 degrees from the Green Bank survey catalog 87GB VIII/14 was observed at three frequencies: 0.96, 3.95, and 11.1GHz. The observations were performed in January and February 1992, in the Northern sector of the RATAN-600 radio telescope. The accuracy of the source right ascensions was improved by a factor of 5-10 (for 70% of the sources the accuracy of the right ascension is 0.1arcsec). About 80% of the objects studied were identified with sources from the Texas survey. File Summary:

Note on Rem: # = The spectral indices were determined from flux densities at 7.6 and 31cm (in the absence of identification with the Texas survey) * = the source is from the Sternberg Astronomical Institute survey list ** = the source is identified with the adjacent lobe *** = the source signal was not distinguished because of interference from a nearby background source.
