Reduction uv-plane
- Quality Fourier-transformed data
(= channel maps): usable
- Notes on "dirty" channel maps: The phases of many uv data change from channel to channel.
- Internal notes for the data-manager
Reduction image-plane
- Quality "cleaned" channel maps: usable
- Notes on "cleaned" channel maps: There are still ring patterns around source position after cleanning.
