OBSERVATIONS OF THE OWENS VALLEY RADIO OBSERVATORY CALIFORNIA INSTITUTE OF TECHNOLOGY PASADENA, CALIFORNIA 1963. 4. ACCURATE MEASUREMENT OF THE DECLINATIONS OF RADIO SOURCES

The two 90-foot steerable paraboloids of the Owens Valley Radio Observatory were used as a two-element interferometer at 960 mc with various separations along a north-south baseline to measure accurately the declinations of a number of radio sources, most of which were of small diameter. The measured values of declination are tabulated for 110 sources with right ascen sions between 0 hours and 14 hours 10 minutes. The standard errors of the measured values range from 2.6 seconds of arc to 46 seconds of arc with an average of 13 seconds of arc. A discussion of the sources of error is included.
