Notes.
The second polyphase filter (van Haarlem et al. 2013) was skipped in the online processing, thus the number of sub-bands and channels was the same, and we will refer to the original sub-bands as channels in the rest of the paper.
The core station CS013 has an incorrect orientation of dipoles with respect to the rest of the array and was always excluded in our observations. Typically two–three other core stations were not available for different reasons, and we used only 20–21 HBA stations out of 24 total. On a few occasions we only had 18–19 HBA stations available.
