Hoi Alessio,
I had a look at the logfiles. We have the following message
BtaMcAssoc::mcFromRecoNeutTrk. mc candidate associate to a reco neutral does not exist.
in both SP3 and SP4. The level is very different though. For two
randomly chosen logfile with 40k events each, I see
SP4: 9876
SP3: 3486
occurences, i.e. SP4 is three times more affected by this. I gather
from CompositionUtils/CompBaseNtpDump.cc that we use "Default" as
microMap, not the GHit-based. Is this right? I'd consider this a bug
and not a feature. Daniele or Ric, could you comment on this, please?
As for the K0S: Did you filter out events with K0S->pi0pi0 only, or
also those with K0S->pi+pi-? It seems that the difference between the
two events classes is larger for SP3 than for SP4.
Cheers,
--U.
