Event yields from data and the expected \ttbar signal and backgrounds for each of the 11 independent categories. Distributions are combined for the two lepton charges and flavors. The bins represent the measured number of jets ({j}) and \cPqb-tagged jets ({b}), with the 4j and 2b categories being inclusive. The bottom panel shows the ratio between the data and the expectations. The relative uncertainty owing to the statistical uncertainty in the simulation, the uncertainty in the normalization of the multijet contribution, and the systematic uncertainty in the total integrated luminosity is represented as a shaded band.
Distributions in the observables used to fit the data with the contributions from all leptons and charges combined. Panels on the left show the distributions in $M(\ell,\cPqb)$, and on the right in $\min M(\ell,\cPqb)$, for events with one and two \cPqb-tagged jets, respectively. From top to bottom, the events correspond to those with 1, 2, 3, or at least 4 jets. The lower plot in each panel shows the ratio between the data and expectations. The relative uncertainty owing to the statistical uncertainty in the simulations, to the uncertainty in the normalization of the contribution from multijet events and to the systematic uncertainty in the total integrated luminosity is represented as a shaded band.

(left) The observed (solid curve) and expected (dashed curve) variation of the likelihood as a function of the signal strength $\mu$ for the distribution-based analysis. The expected curve is obtained by performing the fit using simulated events with $m_\PQt=172.5\GeV$. For comparison, the corresponding curves for the counting cross-check analysis are also shown. The two horizontal lines represent the values in the PLR that are used to determine the 68\% and 95\% confidence level (CL) intervals for the signal strength. (right) Comparison of the values of the signal strength extracted for different combinations of events for the distribution-based default analysis (solid circles) and the cross-check counting analysis (open circles). The horizontal bars represent the total uncertainties, except the beam energy uncertainty. The shaded bands represent the uncertainty in the final combined signal strength obtained from the distribution-based and cross-check analyses.

Estimated change $\Delta\mu$ in the measured signal strength $\mu$, coming from the listed experimental and theoretical sources of uncertainties in the main analysis. The open bars represent the values of the observed impact relative to the fitted signal strength. The values are compared to the expectations (shaded bars) by performing the fit using simulated events with $m_\PQt=172.5\GeV$. The various contributions are shown from the largest to the smallest observed impact.
Dependence of the likelihood on the top quark pole mass (solid curve). The expected dependence from the simulation, using the a priori set of nuisance parameters with their expected values at $m_\PQt=172.5\GeV$, is shown for comparison as the dotted curve. The changes in the likelihood corresponding to the 68\% and 95\% confidence levels (CL) are shown by the dashed lines.
