+\section{Gauge sensitivity}

templates/latex/sens/en-para_0-alt_0-sigma.tex

+The gauge sensitivity \(S\) was calculated according to:
+\[S = \frac{i_\text{c} - i_\text{r}}{i_\text{e}\,p_\text{cal}}\]
+with \(i_\text{c}\) the collector current at calibration pressure \(p_\text{cal}\), \(i_\text{r}\) the collector current
+at residual pressure and \(i_\text{e}\) the emmission current. The gauge sensitivity during use \(S(T_\text{ch})\) is obtained
+from the gas temperature \(T_\text{ch}\) (in kelvins)
+via: \[S(T_\text{ch}) = S(T_0)\frac{T_0}{T_\text{ch}}\]
+with \(T_0\) the gas temperature during calibration.
