Results from the Bland and Altman analysis for the first session (intrasession repeatability).

Parameters	Between first and second measurements		Between first and third measurements		Between second and third measurements
	Mean difference	95% LoA	Mean difference	95% LoA	Mean difference	95% LoA
log⁡(s)	−0.002	−0.211 to 0.207	0.003	−0.240 to 0.245	0.005	−0.166 to 0.176
OSI	0.088	−0.302 to 0.477	0.018	−0.513 to 0.548	−0.070	−0.718 to 0.578

LoA = limit of agreement, log⁡(s) = log(straylight), and OSI = objective scattering index.
