◆ timeshift_ns_hbheho()

float timeshift_ns_hbheho ( float wpksamp )

Timeshift correction for HPDs based on the position of the peak ADC measurement. Allows for an accurate determination of the relative phase of the pulse shape from the HPD. Calculated based on a weighted sum of the -1,0,+1 samples relative to the peak as follows: wpksamp = (0*sample[0] + 1*sample[1] + 2*sample[2]) / (sample[0] + sample[1] + sample[2]) where sample[1] is the maximum ADC sample value.
