Abstract : The two 90-foot steerable paraboloids of the Owens Valley Radio Observatory were used as an eastwest interfermiter to measure the right ascension of 227 radio sources. The observations were made between January, 1960, and July, 1961, at spacings of 195 lambda (958 Mc/s) and 283 lambda (1390 Mc/s). Corrections for resolution and known confusing sources have been evaluated. The standard errors for a source position range between 3 seconds of arc and 20 seconds of arc, with an average value of 9 seconds of arc.
