ZED (top) and V0M (bottom) trigger probabilities per bunch crossing for a typical colliding bunch pair,as a function of time, during the first horizontal and vertical vdM scan. Each time bin corresponds to an acquisition window of $\sim 2$ s. The uncertainties are statistical only. The fit expectation values are also shown, as lines, in each time bin. Time bins during which the beams are being displaced, not considered in the analysis, are not shown.
