Generate event vertices according to a Gaussian distribution transverse to beam direction (given by eta and phi Attention: Units are assumed to be cm and radian!
Generate event vertices according to a Flat distribution. Attention: All values are assumed to be cm!
Generate event vertices according to a Gauss distribution. Attention: All values are assumed to be cm!
Adds the noise only on a subset of strips where it is expected to be greater than a given threshold.
