I _think_ that if you turn off “use2014Gains” it does the right calculation…so thats what I did.  The resulting energies are not completely crazy, though I still have some doubts.  

When the ConditionsManager gets the gains, it says it finds 4 records satisfying the criteria"ecal_gains with” run number 2000-onward  (run number is set to 2000) ;  what does the the hps-java code do in this case?

Though you probably are generating a CalorimeterHit collection in the job, the energies of those hits in GeV aren't correct.  (I haven't verified this because I haven't looked at it lately.)  That's because EcalRawConverterDriver is being run but it doesn't use the convention described by Nathan for the energy algorithm.  This would need to be written according to the formula given in previous emails to the list in order to make CalorimeterHits that make sense for the clustering.

I think we should fix this ASAP so that the calibrations are reasonable.  The existing conditions collection should just be deleted, too, as it isn't usable.

I have calibrated just a few runs with this Driver, and I don't have much idea if there is any pedestal drift (none that I have seen), or at least enough for us to want to store this information by individual run.  I know you stated that there is no significant amount of pedestal drift.  Has this been shown definitively in any analysis/plots e.g. for the cosmic runs?
>>>>>>>>>>>>

Do you want me to generate the pedestal calibrations for these runs and send them to you as text files so you can verify and then load yourself  OR I just can directly load them into the JLAB database myself if you're too busy with ECAL operations.  Probably if I did this I would just assign the collections to the individual run numbers and not a range.
