Dear all,
In this PR I have added the multiplicity in the efficiency correction as well as fixed some issues in the PID processes.

Cheers,
Samuele

How can ptD be negative?

Because to separate positive and negative tracks in the correlator the pt of D meson candidates and associated particles is multiplied by the charge of the particle. This is done in order to not add another column to the table and be able to compute correlations Ds+ - K+ (LS) and Ds+ - K- (ULS)

OK. Well, the name is quite misleading. Just my impression.

If not used in already produced derived data, you can consider to rename it signedPt or something similar. If in already produced derived data instead I would keep it as it is, to avoid unnecessary complications. For the rest the PR looks good to me!
