# Line 7 | Line 7 | is extracted using a profile likelihood
7   uncertainties in the background yield and shape, resolution model and $Z$ yield.
8   In the limit setting we also include the uncertainties from trigger efficiency,
9   lepton selection efficiency, hadronic energy scale and integrated luminosity on the signal efficiency.
10 < The expected LM1 yield is 23 $\pm$ 3 events.
10 > The expected LM1 yield is 23 $\pm$ 2 events.

12   We set upper limits on the non-SM contributions to the high \MET\ and high \Ht\ signal regions.
13   For both regions, we find reasonable agreement between the observed yields and the predictions from MC and from the 2
14   data-driven methods. We choose here to extract the upper limits using the MC prediction for the
15   background estimate. The 95\% CL upper limit is extracted using a Bayesian technique~\cite{ref:cl95cms},
16 < with a log-normal model of nuissance parameter integration assuming 0 signal . The results are summarized in
17 < Table~\ref{tab:results}. Based on these results, we exclude LM1 and LM3.
16 > with a log-normal model of nuissance parameter integration assuming 0 signal efficiency uncertainty.
17 > We also extract a Bayesian 95\% CL upper limit on the quantity $\Delta$. The results are summarized in
18 > Table~\ref{tab:results}.

24   The systematic uncertainties on the ABCD', \ptll, and OF subtraction predictions are discussed in the text. The non-SM yield UL is a
25 < Bayesian 95\% confidence level upper limit. The LM1 and LM3 yields include uncertainties from trigger efficiency,
25 > Bayesian 95\% confidence level upper limit. The LM1 and LM3 yields include uncertainties from MC statistics, trigger efficiency,
26   lepton selection efficiency, hadronic energy scale and integrated luminosity.
