\begin{equation}  \lambda \rightarrow E(\lambda)=\int (f(x)-\lambda)^+ dx.  \end{equation}  Qualitatively, the excess mass $E(\lambda)$ is the sum of contributions $E_C(\lambda)\equiv \int_C (f(x)-\lambda)dx$ coming form connected sets $C[C\subset\{x:f(x)>\lambda\ }]$ $C[C \subset{} {x:f(x)>\lambda}]$
