Dear Annalisa,<br>
<br>
Here are the timelines, along with some notes:<br>
<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but they are a bit out of date; in particular, an issue regarding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>
