There is thus an artificial numeri al time resolution30 \item The pulses have been simulated in steps of 0.2\,ns before digitization. There is thus an artificial numerical time resolution 31 31 limit of $0.2\,\mathrm{ns}/\sqrt{12} \approx 0.06\,\mathrm{ns}$. 32 32 \item The total dynamic range of the entire signal transmission chain was set to infinite, thus the detector has been simulated … … 200 200 section~\ref{sec:mc:convfactors}. 201 201 \par 202 One can see that for small signals, small extrac ion windows yield better resolutions, but extractors which do not202 One can see that for small signals, small extraction windows yield better resolutions, but extractors which do not 203 203 entirely cover the whole pulse, show a clear dependency of the resolution with the signal strength. In the high-gain region, 204 this is valid for all fixed window extractors up to 6~FADC slices integra ion region, all sliding window extractors up to 4~FADC204 this is valid for all fixed window extractors up to 6~FADC slices integration region, all sliding window extractors up to 4~FADC 205 205 slices and for all spline extractors and the digital filter. Among those extractors with a signal dependent resolution, the 206 206 digital filter with 6~FADC slices extraction window shows the smallest dependency, namely 80\% per 50 photo-electrons.
