Abstract
Flux densities at" 8�87 GHz (A = 3�4 cm) have been determined with the Parkes 64 m telescope for 347 radio sources, using an improved on-off integration method. The sources were selected from the Parkes 2700 MHz catalogue as those having estimated flux densities at 8�87 GHz greater than 0'5 Jy (= 0�5 x 1O- 26 Wm-2 Hz-I) and relatively small angular sizes. A total of 156 of the sources are identified with QSOs and 58 with galaxies, and 133 have not been optically identified. Of the 347 sources 101 have been previously measured at this frequency at Parkes. Some of these repeats were made to check variability and others to compare the flux density scale with that of previous measurements. The estimated accuracy of most of the measurements is � 0�034 Jy (r.m.s.) due to noise and confusion and 3�0 % due to other causes.
