Hi Stepan,<br><br>I have processed one file of each 5.7GeV runs to check the T0 time correction that <br>Bayram applied to the EC timing. <br>You can see the result of this test on the "pass0_vec1" table on the online monitoring <br>
web page: <a href="http://www.jlab.org/Hall-B/secure/eg6/cooking/online_sql/monitor.html">http://www.jlab.org/Hall-B/secure/eg6/cooking/online_sql/monitor.html</a><br>It seems that the correction works very well for the whole run range.<br>

I checked couple of EC_CALIB subsystems, it seems you have updated
all of them with your new constants.<br>
<br>
I am thinking to process one file from each 5.7GeV runs to check
the effect of this timing change <br>
on all of them. How that sound for you?<br>

<br>
As a clarification to the
comparison of the first histogram
6600 that you sent in your file. <br>
I produced a similar ones but
after showing the fit result on
them. The attached file
"ect61107_pass0v1.eps" and
"ect61107_ec4.eps" contains the
fit result of histograms 6600 <br>
(only file 01 of a run 61107) from
previous pass0_v1 and yesterday's
test. By looking to the <br>
second fit parameter "P2" you will
notice the effect of the 150ps
correction that you did. <br>
The P2 is the variable that we
store in CSQL database as the mean
of the ECt-SCt, and we <br>
are monitoring online.<br>
As a reference, I grabbed the two
table below from the CSQL
database. The first table contains
<br>
some ECt and RF variables from
pass0_v1, and the second table
contains the same variables <br>
after T0 correction. By comparing
the meanECt between the two
tables, it's clear that the <br>
correction works very well.<br>
