+Simulation table
+~~~~~~~~~~~~~~~~
+
+For some applications, it is useful to provide a simulation file that contains
+the simulation results of the model for the same time points as the
+measurements. This is useful, for example, for comparing the simulation results
+with the measurements, or for assessing simulation reproducibility across tools.
+The simulation table is provided as a tab-separated values (TSV) file with
+the same structure as the measurement table, only that the
+``measurement`` column is replaced by the ``simulation`` column that contains
+the simulation results.
