Below is an example of a file for a VLBI observation that uses the phased VLA. For phasing, a source is used that can also be used as a VLBI phase or fringe fitting reference. All antennas are sent to the reference and VLBI data is taken on it. This is now the prefered style for phasing. Of course the VLAPSRC parameter could also have been used if non-recording scans with only the VLA on the calibrator had been desired.
Note that the main example in the Examples section has a single VLA antenna in it and serves as an example of that type of observing.
