Reduction uv-plane

Quality Fourier-transformed data (= channel maps): reasonable
Notes on "dirty" channel maps: UGC 4637 has been reduced with Miriad and the selfcal has been done.
Internal notes for the data-manager

Reduction image-plane

Quality "cleaned" channel maps: reasonable
Notes on "cleaned" channel maps: There are still residuals of two continuum sources appeared.
