keyword=analysis of sign check runs

On Aug 8 there were some runs on each HRS for sign check.
For the triggered data, the error in the Asy is 1/sqrt(N)
where N = # events. Some runs were much too short, but others
had ~500K events, allowing a 5 sigma measurement of Asy.
Below are the results, sorting T1/T3 by helicity, using "-1"
parameter as the sign argument of HaHelicity::SetState.
The signs agree with HRS scalers and are opposite to Moller,
see halog 178408 and addendum 178411.

run 2361   #T3 (helicity = -1) = 272025
           #T3 (helicity = +1) = 268704
        --> Asy for (+1 - -1) = -0.61 +/- 0.14 %
run 20771  A = -0.68 +/- 0.12 %
run 2364   A = +0.75 +/- 0.15 %
run 20774  A = +0.84 +/- 0.13 %
