Background (R$_{\rm{BB}}$/R$_{\rm{raw}}$), pileup (R$_{\rm{PU}}$/R$_{\rm{BB}}$) and luminosity decay (R$_{\rm{DC}}$/R$_{\rm{PU}}$) correction factors to the T0 (top) and V0 (bottom) rates as a function of the beam separation for one typical pair of colliding bunches during the first p-Pb vertical scan. Due to the different size of the background correction factor for T0 and V0, the two figures have different vertical scales. | ![](https://alice-publications.web.cern.ch/sites/default/files/papers/812/Corrections_T0_3505Y-4860.png ) |
