Specimen	Tomograms included	Averaged repeats	Resolutionat 0.5 Fourier shell correlation criterion (nm)	Resolution at 0.143 Fourier shell correlation criterion (nm)	Used in Figure(s)
S. rosetta slow/fast swimmers*	54	7584	2.2	1.8	3, 4, 5
Central Pair Complex†	28	1323	2.5	2.2	6

^*Resolution was estimated at the base of RS1 from a 64 voxel subvolume.

^†Resolution was estimated at the central portion of the barb from a 64 voxel subvolume.

^‡Resolution was estimated at C1a from a 32 voxel subvolume.
