Why is the gauss function in \second\data\preprocess.py commented out?

[HXB-1997]

Why is the gauss function in \second\data\preprocess.py commented out? Doesn't the paper write the gauss function mask to improve performance?

def gauss_func(x0, y0, h, w, xy):

prob = np.exp(-((xy[:,0] - x0)2/(0.5*w2)) - ((xy[:,1] - y0)2/(0.5*h2) ))

return prob
