    Notes: [Auszug] The observations were made on May 1 and 2, 1976, with the Effelsberg 100-m telescope, which at 22 GHz has a half-power beamwidth (HPBW) of 40?x 43? and, in the zenith, beam and aperture efficiencies of 35 % and 15 %, respectively, of the entire 100-m surface. The primary calibration source, ...

    Notes: [Auszug] Twenty-one declination scans were made at right ascension (1950) 06 h 20 min 11.4 s, which was the interferometric position reported by Davis et al.2. Each scan was 20' long, centred at declination (1950) - 0021'. The average of these scans is shown in Fig. 1. The baseline is not flat because of ...
