Dear Xionghong
Sorry for sending several times, what are the data points in the top 3 panels 
of the page 15? If you just manipulate/apply "()^n" to the fitted function on 
the proton 
data, you do not need data points in each panel, since you just need the 
fitted function. 
However I see the relative point-to-point fluctuation of data seems to be 
reduced 
going from left panel (n=2) to the right panel (n=4), which sounds counter 
intuitive, 
if you really manipulate "()^n" to the data points, or?  
Best regards, ShinIchi
