During project period, fits were done for all data types. It resulted in weird behaviour for 2015 data. TODO: figure out what is causing this, and if we understand all features in these fits.

Mentioned previously maybe a PID issue?

"For Run 2 a new procedure has been introduced to select the PID calibrationsamples directly at trigger level"

Did the new procedure have a poor performance in 2015 for our study?

I'm thinking of dropping 2015, actually. It has little stats and lots of trigger/PID issues, while it has the same energy as 2016, 2017 and 2018 for our purposes of getting the production ratio vs collision energy.

[ ] Make plots of the Xic/Lc yield ratio as function of (only) pT, (only) y, both per year, as well as a full-pt-y yield ratio but as function of year. Depends on #11
[ ] Make plots of the various efficiency ratios (Xic/Lc) as function of pT, y. Depends on #16 #15 .

Yield is done, now, I think

Efficiency ratios next?
