[Clas12_verystrange] Removing untagged photon trigger?

[Michael Dugger]

Lei,

I don't think that my study of the trigger for untagged photons was 
extensive. Where I ran into problems was in estimating the multi-pion at 
low W. To do the estimate correctly would have taken me more time than was 
available. Essentially, the phythia generation breaks down at low W and I 
would have to insert known multi pion event signatures directly into the 
generator.

As you suggest, the best bet is to simply try out a few triggers during an 
actual data run.

Take care,
Michael
