[Rgc] [Clas12_calcom] first draft of pass1 review slides

[Gagik Gavalian]

Hi Silvia,

This may be an irrelevant question, but something strikes me as odd in the slides 50 and 53,
According to slide 50, the gain in single particle reconstruction efficiency (for both charges) is about ~12%

However, on slide 53, at 4 nA, it only shows 2-4% gain in efficiency (as far as one can tell from the graph).
And extrapolated efficiency for 0 nA is above one for the data, which I guess normalization was done on AI, so
it’s the normal procedure.
However, what’s confusing is that on the MC plots, the efficiency is also above one, and it’s not calculated using
extrapolation, but there is an actual point there. Do we reconstruct more tracks in MC when no background is added?

Dear Calcom and RGC,
I have prepared a first draft of the slides for the pass1 review: https://box.in2p3.fr/s/BQHfiJnXY6xKmrA
If you could please check them, it would be great.
Things that will be added shortly:
- SIDIS analysis on the test runs
- Estimates of computing resources
- Back-up slides
- whatever has written "to be done" on the slide :-)
Thank you all for your contribution!
Best regards,
Silvia
