Variability at Frequencies 3.9 and 7.5 GHz: Radio Sources from the Zelenchukskii Survey with Fluxes > 200mJy. Gorshkov, A.G., Konnikova, V. K. <Astron. Zh. 72, 291 (1995)> =1995AZh....72..291G
ADC_Keywords: Radio sources Description: A complete sample of radio sources from the Zelenchukskii survey with fluxes S(3.9GHz)>200mJy and declination range from +4 till +6 degrees were observed at 3.9 and 7.5GHz over the course of seven years. There are one hundred and eighty radio sources in the sample. File Summary:
