Normalized yield of inclusive $\Jpsi$, at forward and backward rapidities, as a function of the normalized charged-particle pseudorapidity density, measured at midrapidity, in \pPb collisions at \eightnnNS. The vertical bars represent the statistical uncertainties. The vertical and horizontal widths of the boxes represent the respective systematic uncertainties for the $\Jpsi$ yields and the multiplicities The dashed line indicates the one-to-one correlation, to guide the eye
