Tayfun
checked Naoko's final Ntuple production version with the new weights.
The new weights also mean new calibration constants.
He said that Naoko's instructions are very clear and easy to follow.
Tayfun looked at the noise with the new code and finds that it has
gone down significantly, with the biggest change in the second
layer.
Richard wanted to know whether all the Ntuples should be re-produced now.
Tayfun said that he'll be working on that. He is working on a script that
automates the job-submission and transmission of Ntuples to UVic.
It takes about 40-80 minutes to create one EMEC Ntuple.
Tayfun is also a `guinea pig' for Jan in trying a new account setup
that will make the user-id numbers used on our machines and the campus unix
more compatible. This causes a few hiccups here and there but should
result in increased security in the end and allow access to the computer centre
new mass storage.
Tamara
looked at the response of (HEC+EMEC) with fixed weights between the two
and finds a drop in response for the middle module. She then applied
a correction obtained from the response of the individual layers and
arrives at a uniform response in x now when plotting (HEC+EMEC).
She hasn't studied the resolution after the correction yet, but
will do so next. Also on her agenda is to let the relative weight
between HEC and EMEC float again and see what that does.
Michel pointed out that the dip in response in the region
of the inter-module gap of the HEC second layer is quite strong.
Interestingly, where there is a dip in the second layer, there
is a peak in the third layer. This obviously has to do with the
development of the shower.
Tamara also mentioned that she looked that Margret's G4 Ntuples
and finds that they are now usable.
Margret
is now looking into the G4 code more deeply by trying to understand
exactly how a HEC module is defined and positioned. Once she understands
that she is planning to put simple objects into the beam herself,
with the idea in mind to create some g4 `material runs'.
For January:
Michel said that Tamara should spend 2 weeks in January to see whether
the new weights affect the hadronic resolution (he suspects the
effect should be smallt, but it needs to be looked at). Then efforts should go toward
preparing for the LArg week where the reduced response in the
middle HEC should be presented.
Richard mentioned that Tayfun should also work on getting a
talk ready for the WRNPP in Lake Louise.
