Here is one of my latest results for h- at twelve degrees



The fit is a power law with the following parameters

dn/deta = 1.11 p0 = 1.54 n = 11.48

I checked your distribution at 1. GeV/c and it is quite close to mine 
but there are more different at higher pt.
I do not apply any correction.
If you send me the macro that made the figure we can compare the 
results in a better way.
I'm still working on the script that make the distribution but I do not 
expect much change.

I would be curious to compare our way of making the spectra.
