This should be fine for our purposes, I think. You're already pouring resources into this, no need to learn an entire new class if this approach is right-ish.

Hi Kolja, all,

This indeed doesn't look trivial. I tried a different approach, where I printed the number of particles that fall into each bin (so not dividing by the total number of truth particles per row), with their sqrt(N) errors, like in the screenshot attached. I guess this can give us a rough estimate of the relative uncertainty of the LUT that I showed last Monday. Do you think this is fine? Or should I still try to look into rigorously propagating the errors with TEfficiency?

Best,

Youqi

Thanks.

Well, it's not trivial. I turned on Sumw2, and I added "error" to the draw command, but the problem is that these histos are generated using

h[pbin][tbin][phibin]->SetBinContent(1, 4, fee[pbin][tbin][phibin]);

I.e., there's no error propagation.

Fixing that will require a bit of work and maths. I found this class which may help, https://root.cern.ch/doc/master/classTEfficiency.html 

Best,

Hi Kolja,

I did p0t0phi0->Draw("colz, text")

Thanks, Youqi! I can run it, what draw commands did you use for the actual plots?

Hi Kolja, all,

I generated the ROOT file for spot checks with the same code as https://github.com/eic/pfRICH/blob/main/readTree.C. I ran the code with

 

root -l 'readTree.C("merged0606.root", "all_out_0606.root", "LUT_0606.txt")'

You can find the input and output files at /gpfs02/eic/youqi/pfRICH/standaloneSimu/pfRICH.

Hi Kolja,

That makes sense. I will submit a batch of jobs to run overnight, so that we can look at the output tomorrow.

Best,

Youqi

I mean, ultimately we want to regenerate the LUTs anyway, there's
nothing prohibiting us from just sending out the jobs for the full
set.

Do we want to redo the exercise from the May campaign by running events throughout the acceptance, but with lower statistics, and then look at the migration matrices? Or do we want to generate events in some specific regions in theta and phi, and just look at the matrices for those specific regions?
