Hallo Urs,

thanka s lot for helping.

I started all over again on the instructions page and first try to get the
first step right. The corresponding logfiles are here:
/afs/slac.stanford.edu/g/babar/work/k/kerstin/new13b/log
and the ouput belonging to the logfiles:
/afs/slac.stanford.edu/g/babar/work/k/kerstin/new13b/ouput
and used the same tcl file as before.
.orig at the end of the names denotes the first try where I followed the
instructions without making any changes. .pidt denotes the second try
where I changed the pidtables link to point to the same as the
pidtables-2000 link.

new13b is what I set up yesterday evening and which I would like to use to
understand the differences. I did not change the PID killing link until
maybe two hours ago.
Having pidtables point to the same place as pidkilling-2000 and comparing
the resulting file with your file in the same variables as yesterday, I
find that I have one events less (848 instead of 849) and one entry in
modeChB less than your file (compared after IBU level). This is a lot
closer but not the same.
What is the PIDmaps(-200n).txt used for? Do I need to set any variable,
link, ... to make sure the right file is used?
Or is there anything else which I need to change with respect to the
instructions to reproduce what you got (before going on and making the
changes I need to dump also the events without Breco candidate)?

Thanks,
Kerstin
