The survey instrument was the 92-m telescope, equipped with a cooled
parametric amplifier centered at 5000 MHz. Beam switching was used, with a
7.2 arcmin separation of the two beams, each of which had a HPBW of 2.7 arcmin.
Observations were made in March and April 1972.
Two small gaps (both at |b|<10d) were excluded.
Those sources in the finding list lying more than 10 deg. from the galactic plane were observed with the 100-m telescope at frequencies of 2.7, 10.7, and 4.9 GHz. Most of those observations were made in August and December 1972 and December 1974.
For the calibration of the flux-density scales, data for three of the standard sources, 3C 123, 3C 147, and 3C 295 were taken from Kellermann et al. (1969; hereafter KPW) for the 2.7- and 4.9-GHz observations. For the latter frequency, the 5.0 GHz flux densities given in KPW were adjusted to 4.9 GHz, using the spectral index computed from the KPW 2.7- and 5.0-GHz flux densities. At 10.7 GHz, the calibration data were taken from Kellermann and Pauliny-Toth (1973). Once the spectral indices of the sources in the survey list had been determined, they were used to correct the measured 4.9-GHz flux densities to 5.0 GHz, for consistency with the previous S surveys.
The typical error for a source having S=0.5 Jy is thus about 2.5, 1.5 and 8 % at 2.7, 5.0 and 10.7 GHz, respectively.
The absolute scale of flux densities is that of KPW at 2.7 and 5.0 GHz and that of Kellermann and Pauliny-Toth (1973) at 10.7 GHz. These scales agree to within 3 % with new, absolute scale of flux densities derived by Baars et al. (1977).
