Hoi Daniele,

It seems  from the logfiles that  muon PidKilling has been  run on the
Beta level. It is done in the same way as for electrons. We know "for
sure" that 

1) the normal muon id has NOT run: 

 AppAST:     0.00 |       0 |      0.00 |        0.00000 |   0.00 |MinimumIoniziongMuonMicroSelection
 AppAST:     0.00 |       0 |      0.00 |        0.00000 |   0.00 |VeryLooseMuonMicroSelection
 AppAST:     0.01 |       0 |      0.00 |        0.00000 |   0.00 |LooseMuonMicroSelection
 AppAST:     0.00 |       0 |      0.00 |        0.00000 |   0.00 |TightMuonMicroSelection
 AppAST:     0.00 |       0 |      0.00 |        0.00000 |   0.00 |VeryTightMuonMicroSelection
 AppAST:     0.00 |       0 |      0.00 |        0.00000 |   0.00 |MuonMicroDispatch

2) BtaMicroPidKilling thinks it has to kill electrons and muons:

 BtaMicroPidKilling:Kill Electrons set on
 BtaMicroPidKilling:Kill Muons set on

All this  is visible in  the output of  the executable, i.e.  not only
from the output of various 'mod talk ... show ...'.

The  message about  "no comments"  is  just a  warning statement,  and
cannot  be changed  since the  hadron people  have  produced PidTables
without comments.   The numbers in the PidTables  seem reasonable. The
no-comment tables concern only  the muon misidentification tables, not
the efficiency tables.

Another  possibility would be  that the  Beta jobs  were run  with the
wrong symlinks 'pidtables', but at  least in that subset I checked for
cocktail MC, it seems that those links were set up correctly.
