Reduction uv-plane

Quality Fourier-transformed data (= channel maps): reasonable
Notes on "dirty" channel maps: no
Internal notes for the data-manager

Reduction image-plane

Quality "cleaned" channel maps: reasonable
Notes on "cleaned" channel maps: The emission come from more than two HI companions, need to do detail analysis further
