<div dir="ltr">I was actually wrong about events ratio, looked at different values. The ratio is even worth for event count. It's 26%/74% for out/in, again this ratio is boosted by weird RCDB event_count values, so we can't trust these numbers.
<div>Also, scaling event number for 10 files doesn't take into account beam shortage later during the run. You can see that there quite the variation of number of events per file (see attached). The histogram entry is 'event_count'/'evio_files_count' for each
run.</div>

<div>No I did not use RCDB</div>

</div>
<div>I used the 10 decoded files from pass0 and counted the number of events in each of these files there</div>
<div>I then used the number of raw files stored on /mss/clas12 to estimate the total number of events for each run</div>

<div dir="ltr">Dear FX,
<div>Do you read number of events per run from RCDB? There is a range of runs where the number of events seems to be wrong. I have included accumulated number of events to the timeline: <a href="https://clas12mon.jlab.org/rga/stats/timeline/" target="_blank">https://clas12mon.jlab.org/rga/stats/timeline/</a></div>
<div>The runs between between 4146 and 4163 seem to have exaggerated values in RCDB and bring the ratio between IN/OUT to 62%/38%</div>

<div dir="ltr">Dear Andrey, all
<div><br>
</div>
<div>With the 10.6 GeV charges you show, I am getting 32% outbending and 68% inbending </div>
<div><br>
</div>
<div>This is a bit different from what I obtained counting the raw number of events (triggers)</div>
<div><br>
</div>
<div>I think the livetime was not very different but the trigger rate was</div>
<div>3932 spring outbending 17 kHz<br>
</div>
<div>4013 spring inbending 14 kHz<br>
</div>
<div>5036 fall inbending 13 kHz</div>
<div>5664 fall outbending 20 kHz</div>
<div><br>
</div>
<div>If I try to correct for this effect I get:</div>
<div>inbending:</div>
(0.14*85.27 + 0.13*47.78) / (0.17*24.367 + 0.14*85.27 + 0.13*47.78 + 0.2*39.045) = 60%
<div>outbending:</div>
(0.17*24.367 + 0.2*39.045) / (0.17*24.367 + 0.14*85.27 + 0.13*47.78 + 0.2*39.045) = 40%
<div><br>
</div>
<div>These numbers reproduce quite closely what I obtained by counting the number of events in all the files from the pass0 selection</div>
<div>I am not sure which way to count is more correct. I said before that the outbending is more favorable both for DVCS and the exclusive phi so maybe I should not insist on this point, but for physics purpose we are interested in the number of events, not
really the Fcup charge directly.</div>
