# Rather ugly data generated from

#    y_peak     = 462     # peak height above background
#    mean       = 1173.24 # central values
#    sigma      = 0.2     # standard deviations
#    def function(x) :
#        return background + y_peak*numpy.exp(-(x-mean)**2/(2*sigma**2))
# With data smeared by x and y uncertainties as listed below.
