Electron contamination

The green points in encountered in our search for the activation model are identified as having high values of propane plus first layer coincidences. Such points can be identified by the filtering criteria:

(VpX1LCntPcu0 + VpX1RCntPcu0) / Q6VpVxXeCntPcu0 >= 0.1

The items in the equation are among the rates available in the Standard2 data.

The cleanest data should be available by eliminating intervals which satisfy this criteria, although we hope to be able to model this background as well in the future.
