for #11405 93f9992

• bugfix to regression input variable for photon energy correction in miniAOD
• the effect is visible only in miniAOD (analysis level; no DQM available) and it is fairly small (see plots posted in Fix sigmaIetaIphi for photon regression #11403)
• jenkins tests pass and comparisons with baseline show no differences

This should be merged in time for re-miniAOD.

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_4_X IBs (tests are also fine) and once validation in the development release cycle CMSSW_7_6_X is complete. This pull request requires discussion in the ORP meeting before it's merged. @davidlange6, @Degano, @smuzaffar

@davidlange6 This also did not make it into 7_4_13 despite being in 7_4_12_patchX...

@gpetruc

[lgray]

Hmm, checking something...

[lgray]

@davidlange6 sorry, false alarm.

[lgray]

@davidlange6 @slava77 indeed, this one was simply not merged before. The only missing one is the fix to the electron classifier BDT calculation...

[lgray]

@gpetruc @davidlange6 Ready to go here, too.
