Radial selections in these plots are based only on the center and outer-ring channels A,B,F.

X and Y “partition” quantities were constructed using only the weighted amplitudes in the inner-ring channels C,D,E, and “triangle plots” were made for events from 13-19 keV (where the calibration peaks are) separately for low-radius, mid-radius, and high-radius events.

Below the same is done for X and Y “delay” quantities based on the relative timing between the inner-ring channels.
