The help section states that the smearing factor, sigma, has a default value of 0.02, however, when --sigma = 0.02 the smearing factor of the resulting plots and data appear to be different. Looking through the code it appears there is a difference between the actual default and the stated default:

dest='sigma', default=0.05,
help='smearing parameter, default 0.02')
