Reduction uv-plane
- Quality Fourier-transformed data
(= channel maps): usable
- Notes on "dirty" channel maps:
- Internal notes for the data-manager
Reduction image-plane
- Quality "cleaned" channel maps: usable
- Notes on "cleaned" channel maps: There is another HI emission nearby UGC4862 and they are merged together in s60 images. It seems there are still continuum emission left in the galaxy line channels.
