Hello Carl

Thanks for the comment. Sorry, I am not familiar with the details of L2Gamma trigger. Do you mean that the rate of BHT2 (threshold = 18) trigger is too high for L2Gamma, such that we need a BHT3 trigger? Thanks.

Best

Hi Rongrong, All—

A note from the peanut gallery…

During 2015, the BHT3 trigger bit was utilized for some other purpose. (I think UPC J/psi, but won’t swear to that.) Therefore, L2Gamma was fed by a funny composite trigger that included BHT and BJP constraints. There is a reasonable chance that the BHT3 trigger bit will be freed up. If so, it would be a natural choice to feed the L2Gamma routine.

Stay Healthy!

Carl
