Left. vertical events; fitted position of the maximum of the charge distribution in VEM as a function of the impact distance to the WCD center. Right: inclined events; fitted position of the maximum of the charge distribution in VEM as a function of the track-length. In both figures the charge is obtained from the sum of the three PMTs. uncertainties of the fit. One can see that there is no dependence on the distance, as observed in the simulations (orange squares): the bottom plot shows that the ratio between the measurements and simulations is within 1%, i.e. at the level of the signal uncertainty, thus giving a further verification of the accuracy of the simulation. P09002 To extend the study to 4 > 1.2 m, we exploit the data collected by the hodoscope in the inclined configuration. The result is shown in the right panel of figure 5, where we compare the fitted position of the maxima of the charge distributions3 determined with measurements (black dots) and simulations (orange squares), as a function of 4. The expected increase of the charge as 4 increases is consistently observed in data and simulations: as shown in the bottom inset, also for inclined events the agreement is at the level of 1%.
