[Eg6_analysis] GPP smearing position factors for the DCs

[Mohammad Hattawy]

Hello Nathan and all,
  Regarding your question about the plots of the superlayers, yes it is
integrated over all the sectors.
For the case of running without gpp at all, in fact gsim_bat set by default
the run number to 100, while gpp set the default run number to 1. So, if i
would like to skip the gpp, the simulated data after gsim will have run
number 100. I attached a text file for the user_ana running error of this
case.

Typically, there are two solutions, the easiest is to add a run number of
100 in the data base. The second is to change the implantation of the
default run number of gsim, compile, and then simulate the data.

Let me know what do u think about this.

-Mohammad.
