Long term averages to suppress background fluctuations. Third telescope (positron UP) is saturated. See link below.
Opposite currents correlations for three telescopes (all PMTs) (pdf, 9 pages).Fine grained heat maps for signal parameter, electron UP. Electron DOWN had a wide collimator and could not resolve detail. Positron UP was saturated so just the fine grained rate heat map is shown, which does have a square region consistent with point-like source.
