In the slides attached labeled RReedHFPico_06252015.pdf, I post my concerns with a quick look at the BEMC in the heavy flavor Pico DSTs.

The main point can be seen in these plots:

The triggered in this case is HT18.  There are clearly hot hot towers, plus this strange structure around ETower = 12 GeV.  There is also the issue at eta ~ 0.  The towers that cause the spike at 32 GeV are actually coming from very few towers, but they have a lot of counts.  These are not always overlapping with towers that show up red on the right.

The relevant code is:

unsigned int nepid = mPicoDst->numberOfEmcPidTraits();

for (int i = 0;i<nepid;i++){ //with check that btowerId > 0 and that emctraits exists

PicoEmcPidTraits* emctraits = mPicoDst->emcPidTraits(i);

he0->Fill(emctraits->e0());}

hTowerId->Fill(emctraits->btowId());

I got the h-f position from:

StEmcGeom *geomBemc = StEmcGeom::getEmcGeom(1);

geomBemc->getEta(emctraits->btowId(),eta);

geomBemc->getPhi(emctraits->btowId(),phi);

Is there a calibration maker I am missing?
