Issues encountered this weekConcern
Checked out all triggers with muons.
Most triggers have placed L2 cuts far away from L3, usually equal to L1 thresholds.
If L2 threshold is moved too close to L3, one starts to have inefficiencies due to the L2 resolution (see next slide)
As the L2 cut has (should have) no impact on physics, only on CPU timing (which is expected to be very small), we recommend to move all L2 cuts to correspond to the L1 thresholds.
(L1 thresholds are tuned so that they are 90% efficient at the cut value,so they correspond to effectively lower cuts.)
Some L2 turn-on curves are shown on next page to illustrate the issue.
