Abstract

Abstract : The two 90-foot steerable paraboloids of the Owens Valley Radio Observatory were used as a twoelement interferometer with a north-south baseline to measure accurately the declinations of 90 radio sources with right ascensions between 9 hours 50 minutes and 24 hours. The antenna separation was 200 feet and the observing frequency was 1390 Mc/s. The average standard error of the measured declinations is = 12 seconds of arc. (Author)
