*
In lattice units, if not specified otherwise. Real values are given to enable a comparison with experimental data.
†
To compare shown values with measured data, we can assume that 0.2 × 10−6 = 1 cmH2O. Therefore, the maximum pressure that can be produced equals kM = 20 cmH2O.
‡
For better readability, we leave out the factor of 10−7 when referring to transwall pressure in the main text.
