... When using a single spectral window, and observing spectral lines, the bandwidth of the ATCA can be problematically narrow, or the channel widths can be too coarse. ... A partial work around for this situation is to use the two ATCA frequency bands to observe in adjacent somewhat overlapping windows, and using the same bandwidths and channel counts for the two windows. ... In so doing, it handles any overlap region between the two windows in a sensible fashion. ...
