Comparison of particle diameter and size distribution (std) between manufacturing specifications and microscopy image processing estimations.

Grit-size (per label)	Manufacturers specifications ($\pm \mathrm{std}$)	Determined via microscopy ($\pm \mathrm{std}$)
400 grit ($\mu \mathrm{m}$)	$17.3\pm 8.0$	$17.1\pm 11.0$
800 grit ($\mu \mathrm{m}$)	$6.5\pm 3.0$	$6.7\pm 4.9$
1000 grit ($\mu \mathrm{m}$)	$4.5\pm 1.0$	$4.1\pm 2.8$
1200 grit ($\mu \mathrm{m}$)	$3.0\pm 1.0$	$3.8\pm 2.3$
