[math]\gamma[/math]-peak positions are shifted w.r.t. each other. If we wanna calculate the asymmetry as a function of TOF for each channel it is necessary to match the positions of centroids of [math]\gamma[/math]-peaks. However, one needs to take into account the difference between channel-to-TOF calibration coefficients for each detector.

Calibration used 0.19 ns/channel. [math]\gamma[/math]-peak positions were matched manually.


The following plot was drawn using upper plot and formula for calculation of asymmetry placed at [[1]]
