Comparison Slow Simulator and Real data dAu Min Bias

The Distribution of the number of hits-on-global-track is NOT the same for Real Data and Simulation with Hijing through the Slow Simulator (?) What happens with all this 10-hit-on-track ? The used Gain Table is not good enough to reproduce the holes?

The residuals are much better for Simulation than for Real data. We still need to do something here )-:
