Good news that after having corrected the Python error your measured distribution is less extreme!
I have two concerns about your extrapolation of the seed density distribution:
- When fitting or extrapolating a density distribution function, you need to take care that each class has the same Δr. The integral over the density distribution must be equal to the total number N of particles! In your plot of the measured distribution, for example, the bending of the curve is probably not real, it is just because Δr is smaller for the class with radius 85 nm...
- Your tabulated distributions cannot contain the same value of r twice (0.05). Furthermore, at least in the MICRESS input, the classes must be put in order with decreasing radius!
