Schema
Illustration of the cut-sky with gamma rays distributed on it. Patches of radius R
degrees are centered on the highest energy gamma rays. In those patches we
test if the lower energy photons are distributed along left- or right-handed spirals.

CP odd statistics, Qx10^-6, versus patch radius R in degrees for the 6 different energy (E1,E2) combinations. E3 is always taken to be 50 GeV. On the left are results of Tashiro's routines; on the right are consistent results obtained using Ferrer's routines. Spreads of the Monte Carlo simulations are shown as magenta error bars in Tashiro's plots, and as green error bars in Ferrer's plots.
