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