what is a bit-wise or of

• kPt Weight according to transverse momentum
• kEta Weight according to Pseudo-rapidity
• kPID Weight according to particle type
• kCent Weight according to centrality
• kB Weight according to impact parameter.

Note, that kCent and kB are mutually exclusive

type can be one of

• 0 No weighting
• 1 Pt is weighted as mean of \(v_2{2}\) and \(v_2{4}\) from 40-50% centrality, unity weight for p, other for \(\pi\), other particles fixed, and the width of the \(\eta\) Gaussian is 9
• 2 Pt is weighted by \(v_2{2}\) from 40-50% centrality, fixed PID weight, and the width of the \(\eta\) Gaussian is 3
• 3 Pt is weighted by \(v_2{4}\) from 30-40% centrality, unity weight for p, other for \(\pi\), other particles fixed, and the width of the \(\eta\) Gaussian is 15
• 4 Pt is weighted by \(v_2{4}\) from 40-50% centrality, unity weight for p, other for \(\pi\), other particles fixed, and the width of the \(\eta\) Gaussian is 9
