BadECAL filter

[mcremone]

Implement BadECAL filter from here: https://github.com/sidnarayanan/PandaAnalysis/search?q=cBadECALJets&unscoped_q=cBadECALJets

Started here:

https://github.com/LPC-DM/decaf/blob/master/grinder/utils/corrections.py#L123-L128

this should retrieve the weight that is necessary to compute the filter as shown here:

@trtomei would you mind finishing implementing it?

Hi @mcremone

Yes, it is on my TODO list. I have time allocated for this tomorrow morning!

thanks

So, I have studied this a bit... this does not seem to be the filter described in:
https://twiki.cern.ch/twiki/bin/viewauth/CMS/MissingETOptionalFiltersRun2#How_to_run_ecal_BadCalibReducedM

This seems to be some filter that filters events wholesale if jets coincide with some list of bad crystals or towers. I have found no hint of where is this list, and where does it come from. I suggest we acquire more information before going ahead with this.

Following up the discussion on slack, I agree it would be good implementing something along the lines of what is implemented in https://github.com/TreeMaker/ecalBadCalibFilterLists/tree/master/data
