Abstract (from CDS):

In a VLBI test experiment between the IRAM 3Om telescope at Pico Veleta, Spain, and one 15-m telescope of the IRAM interferometer on Plateau de Bure, France, we detected fringes at 215 GHz with signal to noise ratios between 6 8 and 10.2. On this 1147km long distance, of 0.28-0.43 milli arcseconds projected fringe spacing at 215 GHz, we have 8 independent detections of the sources 3C273, 3C279 and 2145+067 The clock and fringe rates at 215 GHz are consistent with those derived from VLBI measurements at 86 GHz made at the beginning or end of the 215 GHz observations. The coherence time at 215 GHz were of the order of 10 seconds, most probably limited by the atmosphere.
