EnergyInDeadE{B,E}_FE warnings from hltEcalRecHit

[missirol]

Looking at log files of HLT jobs running online, one can find the following warnings. I see these warnings already in a log from 2023, so they are not new. In fact, they were already mentioned in #41456. Still, I would kindly ask experts to comment on what these warnings mean, and whether or not any action should be taken.

@jhakala @argiro as ECAL Reco contacts, can you please have a look?

[ReyerBand]

These warnings are caused by channels that are already masked in reco but not the trigger, so they report the energy calculated from the TP. The level of these should be downgraded from LogWarning to LogInfo in the future.

@ReyerBand
thanks for having a look

These warnings are caused by channels that are already masked in reco but not the trigger.

For my education, It is not very clear what trigger means in this context. These messages appear in the trigger (HLT) logs. Do you mean in the trigger primitives?
What's the consequence on the HLT decision?

The level of these should be downgraded from LogWarning to LogInfo in the future.

Should these channels be masked at HLT as well, instead? In other worlds is it safe to remove the warnings?

[ReyerBand]

@mmusich Sorry for my imprecise description - I did mean the trigger primitives. These channels have a dead data readout but the TP energy info can be used. These "warnings" are just reporting that TP energy, and it's safe to remove them.
