**Figure Caption**

Ratio of dissociative-to-exclusive \jpsi photoproduction cross sections measured by ALICE in \pPb UPCs at \eightsixteen and compared with H1 measurements~. The uncertainties of the data points are the quadratic sum of the statistical andsystematic uncertainties The experimental uncertainties for the H1 data are computed assuming completely independent uncertainties for the exclusive and dissociative cross sections. The measurements are compared with the CCT model~ and a model by Mäntysaari--Schenke (MS)~. The uncertainty band of the MS model corresponds to the statistical uncertainty of the calculation.
