[G12] [Fwd: [g13] Ratio of results files to original data]

[Pawel Nadel-Turonski]

Hi All,

Since it is late in France right now, this is a file with high-level 
information used for Daria's analysis of the beam asymmetry in single 
pion production on the neutron. To save time it will be run during the 
recooking, for which it will also provide a convenient form of 
monitoring. It is a physics and not a data format issue. The question 
was only how much extra monitoring information we want to add.

Cheers,

     Pawel
