Constructor Detail

GaussianBoxFunction

public GaussianBoxFunction(double xmin,
                           double xmax,
                           double ymin,
                           double ymax)

Public constructor called by jas.swingstudio. It initializes the parameters to correspond with a calorimeter with a resolution of 1% + 15% / sqrt(E).

Parameters:

xmin - lower edge of the histogram

xmax - upper edge of the histogram

ymin - lower edge of histogram

ymax - upper edge of histogram
