Pad 1-4 are without time-dependent gain corrections and each one is for some specific
way of QT matrix generation from MuDst. One of them would be correct for defining QT-matrix.
For the correct  one only, gains and t-dependent gain corrections will be picked up correctly and
mapping of eta-phi would be correct.  Pads 5-8 are repeating the same configurations but
wit time-dependent gain corrections. Pads 9-12 are with confuration like pad-1 but
thay includes other detectors in the analysis.

The attached pdf files:
full.pdf is with data samples randomly selected from days 86 to 94 (for 400 jobs each with 200 events).
Only FMS triggers are used.  The spikes in \Eta and large energy jets in the file are for some datasets which are bad.
If the dtasets are segented in 20 files intervals, we can see the bad ones are part_240_260.pdf and part_280_300.pdf.
So the events making the life worse might be coming from some specific runs or days.

Pi0 mass peak for the first eight configurations : 

For a wide R=1.2, we expect to cover all the decay photons from pi0's particles.

Red Markers   : pairing ot any two photns in a jet 
Black Markers : pairing ot any two photns where one coming from a jet in one event and the other one is from a different event.  
Bule                : signal (red-black, after background normalization)

Here \pt of each pair for signals > 2.0 GeV/c and for background > 0.9 GeV/c

For whole detector :

eta of pi0's > 3.2

eta of pi0's < 3.2
