Reduction uv-plane
- Quality Fourier-transformed data
(= channel maps): reasonable
- Notes on "dirty" channel maps:There is a bright and dominant continuum source in the field away from the center. It remains in many channels after subtracting continuum in Gipsy phase. For solving the problem the selfcal is used for all channels (only solving phase corrections) with one point source model.
