Reduction uv-plane
- Quality Fourier-transformed data
(= channel maps): usable
- Notes on "dirty" channel maps: There are bad data around ch61(it is ch60 for images).
- Internal notes for the data-manager
Reduction image-plane
- Quality "cleaned" channel maps: usable
- Notes on "cleaned" channel maps: There are still some grating ring structures around source position after cleanning.
