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.
!!! For 10 src fluxex were corrected by authors 31/10/97!!! (S.Trushkin)
