Dear Annalisa,<br>
<br>
Here are the timelines, along with some notes:<br>
<br>
<a class="moz-txt-link-freetext"
href="https://clas12mon.jlab.org/dilks/rgk_test/timeline/"
moz-do-not-send="true">https://clas12mon.jlab.org/dilks/rgk_test/timeline/</a><br>
<br>
-- beam spin asymmetry<br>
- pi+ beam spin asymmetry has the wrong sign, likely because
RGK helicity<br>
assignment is opposite what RGA and RGB use; it's simple to
fix and can be<br>
done later when reading pass1 data. It is also interesting
to note that the<br>
magnitude of the pi+ asymmetry is around 4% for RGK, but for
RGA and RGB it<br>
is 2%.<br>
<br>
-- electron trigger yield normalized values<br>
- the four runs have a wide range of FC-normalized electron
trigger yields;<br>
therefore the QA cuts are defined separately for each run.
These normalized<br>
yields are nearly constant within each of the runs, except
for the first file of run<br>
5958 (but that's perfectly normal, sometimes the first or
last file of a run does this)<br>
<br>
All the other timelines look normal, but there is a jump in
the pion pT between 5823 and 5893, as well as x and Q2<br>
<br>
I've also attached some slides which describe how the QA
works, but they are a bit out of date; in particular, an issue
regarding the livetime was fixed, so there's no longer a need
for a livetime>1 defect bit.<br>
<br>

Yes, I can prepare timelines, but I'm not available this
Friday (June 5th) to give a presentation. I will send you
an update when they are ready.<br>

RG-K will face the pass1 review next Friday at 8:30 Jlab
time. We have fully cooked four runs<br>
<br>
5700, 5823, 5893, 5958<br>
<br>
that are available at:<br>
/volatile/clas12/rg-k/production/pass0/v1_1.1.41/calib/train/<br>
<br>
Would you be available to run your quality plot codes on
those 4 runs, to show the potetntial of the dataset?<br>
Would you be available to give a short presentation
about the results?<br>
Thank you in advance for your collaboration<br>
Annalisa<br>
