Appendix 1—table 1. Best fit parameters.

The average domain lengths (approximately the size of the cell’s long axis) on which the myosin profiles were given were ${\displaystyle L_{AB}=27.4\mu m}$, ${\displaystyle L_{ABa}=19.5\mu m}$ and ${\displaystyle L_{ABp}=17.9\mu m}$. The corresponding fits are shown in Figure 1—figure supplement 8.

Cell type	${\displaystyle \ell }$ [µm]	$v_T$ [µm/min]	$v_{\tau }$ [µm/min]
AB	18.7	0.15	0.25
ABa	10.4	0.19	0.15
ABp	8.2	0.4	0.4
