3.3 Available Resolution

Table 3.4 gives an overview of the angular resolution available from the Plateau de Bure interferometer and the CMVA-VLBA mm-wavelength VLBI-arrays (USA + Europe). The table gives for comparison the parameters of the Pico Veleta 30-m telescope (Spain). The table gives also the linear scale corresponding to the angular resolution $\Theta$ for a source located at 50 Million pc distance.
