STAR task force for evaluating tracking efficiency uncertainty

[Robert Líčeník <licenik AT ujf.cas.cz>]

Hi everyone,

I also missed the time zone change in the US, so I forgot to join. Let me write the update regarding the cosmics analysis here:

We realized that generating cosmic tracks directly from data files is very inefficient, since we only care about cosmic tracks that resemble real collision data tracks.

Therefore, we created a THnSparse with dca and momentum distribution from real tracks after the desired cuts and will simulate the tracks from this histogram.

Petr is still looking into how to generate tracks from histogram using the St_geant_Maker, but once we get this to work, we should have the simulation done very soon.

Cheers,

Robert

Hi Petr, I believe that you are still on winter time. Let's check this in one hour.
