$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, P1, P2 , P3, P4, p5
1 A hbarW sigx sigy xc yc
2 A hbarW sigx sigy xc yc
3 A hbarW sigx sigy xc yc
4 A hbarW sigy yc
5 A hbarW sigx xc 

For function type

1: If hbarW > Eg, $G(x,y) = A * exp(-\frac{(x-xc)^{2}}{2*sigx^{2}}) * exp(-\frac{(y-yc)^{2}}{2*sigy^{2}})$
2: If hbarW > Eg, $G(x,y) = A * exp(-\frac{(x-xc)^{2}}{sigx^{2}}) * exp(-\frac{-|(y-yc)|}{sigy})$
3: If hbarW > Eg, $G(x,y) = A * exp(-\frac{(y-yc)^{2}}{sigy^{2}}) * exp(-\frac{-|(x-xc)|}{sigx})$
4: If hbarW > Eg, $G(x,y) = A * exp(-\frac{-|(y-yc)|}{sigy})$
5: If hbarW > Eg, $G(x,y) = A * exp(-\frac{-|(x-xc)|}{sigx})$
