Subject: Possibility to specify  GEM readout option
X-Git-Url: http://git.uio.no/git/?p=u%2Fmrichter%2FAliRoot.git;a=commitdiff_plain;h=a120cd1d5692c5a1a12e3382c92d289ddc48f125

Possibility to specify  GEM readout option
PRF for GEM readout  AliTPCprf2dGEM.root
PRF Generated by macro   AliTPCCreatePRFGEM.C
PRF approximated as a gaussian with width ~ 0.025 cm given by diffusion

To enable GEM readout modify the Config.C:

  AliTPC *TPC = new AliTPCv2("TPC", "Default");
        TPC->SetGEM(1);
