Dear Jiat Li,
Flair calls usrxsuw to produce the _tab.lis files, and plots the data as
written in the _tab.lis files
So:
if you process data files with flair, you'll get automatically the tab_lis
files with values
And: flair plots (correctly!) the data as it is, per GeV , not multiplied
wby the bin width.
Multiplication by y bin width is unormally used to get integrated values.
You do NOT need to multiply by 2pi or 4pi. this is true only for results
of the usxrea program, not usxsuw.
Hope this helps
Paola
