 \subsubsection*{Purity}
-Once both electromagnetic collimation and tracking isolation are applied, a threshold on the $p_T$ of the $\tau$-jet candidate is requested to purify the collection. This procedure selects $\tau$ leptons decaying hadronically with a typical efficiency of $60\%$.

 \textsc{Delphes} performs a fast simulation of a collider experiment. 
-Its quality and validity are assessed by comparing to resolution of the reconstructed data to the \textsc{cms} detector expectations. 
+Its performances in terms of computing time and data size are directly proportional to the number of simulated events and on the considered physics process. As an example, $10,000$ $pp \rightarrow t \bar t X$ events are processed in $110~\textrm{s}$ on a regular laptop and use less than $250~\textrm{MB}$ of disk space.
+The quality and validity of the output are assessed by comparing to resolution of the reconstructed data to the \textsc{cms} detector expectations. 
 
 Electrons and muons are by construction equal to the experiment designs, as the Gaussian smearing of their kinematics properties is defined according to their resolutions.
