Update on Bogus/Aslund/bbsim Validation:
-
I have generated 5,000 single mu--'s (500 MeV) with the fixed version of BbsimModule, and reconstructed with 8.1.0 Beta. If you recall, we used to see the problem of much wider BBSIM/Beta track parameters comparing to Aslund/Bogus (as shown, for example, here).
-
But now the agreement is much, much better! See these plots (both Aslund and bbsim/Beta generated/reconstructed a sample of 5,000 events, but there's nothing we can do about Beta reconstruction efficiency...).
-
This means that Bogus agrees quite well with both Aslund and bbsim/Beta. Which in turn means it's time for...
