A kind of analysis

[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 (neutron energy) 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.

This is what we have if we superimpose TOF-spectra within one plot. It was used used the average channel-to-TOF calibration coefficient (0.179+0.186+0.19)/3 = 0.185 ns/channel (Is it okay to do that?).

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]]
