摘要：
Most currently available counts of radio sources at frequencies > 5 GHz are restricted to relatively bright sources. Observations made at NRAO's VLA have, however, provided counts of very faint sources ( S less than or similar to 1 mJy) at 8.5 GHz. Here we extend the 8.5 GHz VLA source counts to higher flux densities using both archival data and a brief, blind VLA survey at 8.5 GHz. We thus link the faint source counts to earlier source counts at S greater than or similar to 30 mJy. The new counts of radio sources at 8.5 GHz hold no surprises.
