$usespecgen

$usespecgen is the command to put generation profile with a specific function, which is mostly Gaussian shape generation profile.

$usespecgen
N_region
func_type A B sigx, sigy, xc, yc

For function type

1: $G(x,y) = A*B * exp(-\frac{(x-xc)^{2}}{sigx^{2}}) * exp(-\frac{(y-yc)^{2}}{sigy^{2}})$
2: $G(x,y) = A*B * exp(-\frac{(x-xc)^{2}}{sigx^{2}})* exp(-\frac{(x-xc)^{2}}{sigx^{2}})* exp(-\frac{-|(y-yc)|}{sigy})$
3: $G(x,y) = A*B * exp(-\frac{(x-xc)^{2}}{sigx^{2}})* exp(-\frac{(x-xc)^{2}}{sigx^{2}}) * exp(-\frac{-|(x-xc)|}{sigx})$
