I got the two-dimensional map of the BS from Hirose-san.
I will try to implement these data into the "LightTools" software in the next days.

At the same time, I tried to fit the one-dimensional PSD with the K-correlation model with only limited success.
It seems that this particular model is not suitable for the data...or the data aren't enough.
From the map it should also be possible to calculate the two-dimensional PSD and to fit these data instead of the one-dimensional one.
I would like to try these calculations also during the next days to see how far I can use the PSD for the scattering Paper I am now writing.
