    Description
    The profile likelihood fits used to maximise the sensitivity of Higgs searches can obtain significant constraints on the input systematic uncertainties. We discuss the legitimacy of such constraints and, in particular, whether these constraints can, and should, be interpreted as measurements. The fit used in the CMS H->WW analysis will be discussed in some detail as a specific example of such a fit.
