Detailed Description

Histogram and fitter class for drift time and pulsehight spectra The rising slope is fitted by a fermi-function: \(f(t)=r_{u,0} + \frac{A}{1+exp((t_0 - t)/T_0}\).

The falling slope is fitted by \(g(t)=r_{u,max} + \frac{e(t,a,b)}{1+exp((t_{max} - t)/T_{max}}\) where \(e(t, a, b) = a e^{bt}\). A pattern recognition determines the fit ranges and the parameters \(r_u\), \(A\), \(a\) and \(b\).
