 | Distributions of (top) \mmsq, (middle) decay time, and (bottom) $Z$ of the signal data, overlaid with projections of the fit model with all normalization and shape parameters at their best-fit values. Below each panel differences between the data and fit are shown, normalized by the Poisson uncertainty in the data; the dashed lines are at the values $\pm 2$. |
