 Hi Igal,
would you share inv. mass plots with the peaks at wrong position.

 Thank you.
Ilya

Subject: [Halld-cpp] Issues with simulated data

Good morning, CPP/NPPeurs,

I simulated Primakoff photoproduction of pi^0 & eta off Lead nucleus and encountered several issues.
1/ Beam photon list is empty for most of the runs
2/ Diphoton invariant mass for pi^0 & eta candidates peaking at the wrong mass.

It will help me if I am getting any feedback from any of you. Was this notice? Was is already solved? How?

These are my jana options:

NTHREADS 12

TRKFIT:HYPOTHESES 2,3,8,9,11,12,14,15
KALMAN:ADD_VERTEX_POINT 1    # add upstream vertex point
PID:ADD_FCAL_DATA_FOR_CPP 1 # add FCal related quantities to REST
MONITOR:MIN_TRACKING_FOM 1e-10
MATCHING:IGNORE_START_COUNTER 1
BCAL_TDC_Timing:DONT_USE_SC 1

MCTHROWN:TAGCHECK 1

JANA_CALIB_CONTEXT variation=mc

tks ig.
