@Wile_E_Coyote I’m sure you must have seen the NKG function. There are actually only 3 parameters in the NKG function Ne, s and rM. In my case, I have directly put the value of rM (moliere radius) instead of taking it as a parameter because it is known for that particular geographical place and that’s why my curve was not coming out right. On the other hand, you’ve taken it as a parameter and it spits out that value for which the curve is fitting well, but the problem now is this value of rM is not correctly matching with the calculated one.
So the question that really needs to be asked is why my simulated points are not generated correctly such that they fit the NKG function for rM=103. It may be due to wrong input of parameters, which I doubt, but needs to be checked.
