Imaging capability of the Mitaka VSOP correlator Original Research Article

We have made a comparison between data between the Mitaka and Penticton correlators, using VSOP observations of NRAO530 at 1.6 GHz. After calibrating the data with AIPS we find excellent agreement with the closure phase between the data processed at the two correlators. The images made from both data sets also agree well. We have made other VSOP images of OQ208 at 1.6 GHz, and 3C395, J2011-15 at 5 GHz from data correlated by the Mitaka correlator. These images are all consistent with ground-only VLBI results at higher frequencies, and demonstrate the capability of the Mitaka correlator as a VSOP correlator.
