Fig. 3


Example of a channel map from one of the processed sub-region cubes (Cube 9) from the WVFS cross-correlation data. The inner region is well sampled by the pointings and the noise is uniform, while emission at the edges is noisier. There is 25% overlap in right ascension between adjacent cubes. Unfortunately the coordinates could not be shown in this plot due to projection effects, as explained in the text.
