STAR task force for evaluating tracking efficiency uncertainty

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

Hi everyone,

thanks to Petr, who produced MuDsts and picoDsts from daq files in both SL12d_embed and SL13b_embed libraries, we can now conclude that the differences between the official production and the production done by Dmitry (and used for embedding in his study) is very likely due to the difference between the two libraries. See attached slides for the comparison plots. For simplicity, black and green points are from SL12d(_embed) and other points are from SL13b_embed. 

Would anyone happen to remember what changed between these two libraries that might cause such a large difference in refmult and other track-related quantities?

Thanks,

Robert
