The GMVA combines the eight 3mm receiver equipped stations of the VLBA and up to six European observatories, including Effelsberg, Onsala, Metsahovi, Pico Veleta, Plateau de Bure, and since 2012, Yebes. Data were recorded at 512 Mbit/s, with eight 8MHz channels, in dual polarisation. Onsala and Yebes observed in left circular polarisation (LCP) only. For these stations, LCP was assumed to be equal to RCP and hence Stokes I. Scans of approximately 7 minutes every 15 minutes were recorded with pointing and calibration performed on European stations in the gaps between scans.(2 data files).
