Hi Stefano,

I do not apply any cuts for this distribution.
I want to understand also what is going on between 0 to 7 degree.
Whether is it lambda specific due to V0 decay or some bug in the code.

Idea behind this plot is that we can use stt alone mode, which has a best acceptance in the fast simulation.
Quote:

fastSim->AddDetector("ScSttAlone", "thtMin=0. thtMax=160. ptmin=0.0 pmin=0.0 pRes=0.001 thtRes=0.001 phiRes=0.001 efficiency=1.0");

With option "EmcBar Drc Dsc", only above STT alone will be used and can see what will happen in the acceptance.

If I use standard mode with stt+mvd+gem in addition FwSpec, the spectrum looks same, cannot find any lambdabar between 0 and 7 region.

Best wishes,
Donghee
