Calibration results for membrane time constants. Before calibration (left), the distribution of ${\tau }_{\text{m}}$ values has a median of $\widetilde{{\tau }_{\text{m}}}=15.1$ ms with 20th and 80th percentiles of ${\tau }_{\text{m}}^{20}=10.3$ ms and ${\tau }_{\text{m}}^{80}=22.1$ ms, respectively. After calibration (right), the distribution median lies closer to the target value and narrows significantly: $\widetilde{{\tau }_{\text{m}}}=11.2\text{ms}$ with ${\tau }_{\text{m}}^{20}=10.6\text{ms}$ and ${\tau }_{\text{m}}^{80}=12.0\text{ms}\text{.}$ Two neurons were discarded, because the automated calibration algorithm did not converge.
