RC_mean and RC_max ranges as defined by EARL [8], compared with RC results for all spheres at 10 min and 62 s scan duration

Sphere volume (mL)	EARL: RCmean range	RCmean at t = 600 s	RCmean at t = 62 s	EARL: RCmax range	RCmax at t = 600 s	RCmax at t = 62 s
26.52	0.76–0.89	0.79	0.80	0.95–1.16	0.98	1.05
11.49	0.72–0.85	0.75	0.74	0.91–1.13	0.96	1.04
5.57	0.63–0.78	0.72	0.69	0.83–1.09	0.97	0.94
2.57	0.57–0.73	0.68	0.64	0.73–1.01	0.93	0.90
1.15	0.44–0.60	0.44	0.48	0.59–0.85	0.59	0.71
0.52	0.27–0.38	0.33	0.27	0.31–0.49	0.44	0.40

For all spheres, RCs were within EARL specifications
