Summary of the BCID-averaged corrections to ${\sigma }_{\mathrm{vis}}$ (in %) obtained with the vdM scan calibrations at $\sqrt{s}=13\text{TeV}$ in 2015 and 2016. When a range is shown, it is because of possible scan-to-scan variations. To obtain the impact on ${\sigma }_{\mathrm{vis}}$, each correction is consecutively included, the fits are redone following the order below, and the result is compared with the baseline. The impact from transverse factorizability is obtained separately (as discussed in Sect. 4.4)
