Non-Pointing Photon Analysis: Comparing Photon Significances in Barrel/Endcap
Preliminary significance calculations using only the photon timing.
Define:
significance = sqrt( -2*(b*log(1 + s/b ) -s ) )
Nsignal = number of signal events in SR with ph_t > 2 ns
Nbkg = scaled* number of data events in CR with ph_t > 2 ns
*scaled --> scale the data events in the CR to the number in the SR (I am using the timing shape of the CR)
Note: I am currently using exclusive timing shapes for the background (ie, use scaled timing shape from data CR_1el_1ph and timing shape of signal SR_1el_1ph to calculate
significance).
Next step: using binned log likelihood using photon timing
