Table 4.

Eight waveform groups characterized by high/low values of (V_max, T*, V*). In column 2, H = “high”, L = “low”. $\overline{\mathrm{Q}}$ is determined from Eq. 2 and well estimated by Eq. 6. Group numbers are ordered from maximum to minimum $\overline{\mathrm{Q}}$. Data needed to reconstruct these curves is provided in supplemental material.
