[Frost] helicity info in g9b data

[Franz Klein]

Hi,
this morning I claimed that the helicity information was correctly 
extracted for most of the runs ... but that was not correct: by chance I 
looked into cooked files where it worked!
Since we had delayed reporting, in part by 8 helicity intervals, in part 
by 16 intervals, I have to get the correct sequence of helicity scaler 
events (or cannot resolve the helicity info for a given helicity 
interval). However, often the helicity info in the gated and ungated 
scaler banks did not match during g9b, so I have to figure out how to 
solve that over the next days ...
This concerns ~60% of the cooked files (as you see by chance I didn't 
look into bad files ...)

When I am done with that, I will write a wiki page about helicity info, 
etc. (similar to

Greetings
Franz
