Expected and observed 95 % CL exclusion limits for the pMSSM model with well-tempered neutralinos as a function of $M_1$ and a $m_{\tilde{q}L3}$ or b $m_{{\tilde{t}}_{\mathrm{R}}^{}}$. The limit of a is obtained as the combination of the t0L, t1L, tb and SS3L analyses, while the t0L analysis is used for b. The signal region yielding the smallest CL${}_s$ value for the signal-plus-background hypothesis is used for each point. The dashed black line indicates the expected limit, and the yellow band indicates the $\pm 1\mathit{\sigma }$ uncertainties, which include all uncertainties except the theoretical uncertainties in the signal. The red solid line indicates the observed limit, and the red dotted lines indicate the sensitivity to $\pm 1\mathit{\sigma }$ variations of the signal theoretical. The dashed and dotted grey lines indicate a constant value of the stop and sbottom masses, while the dashed light-blue line indicates a constant value of the neutralino mass
