Table 2.

Statistics on number of beads for some random STPT slices.

Slice no.	No. of beads	Average radius (μm)	Dispersion (μm)	False positives (%)
1	332	47	11	0.90
2	327	49	11	0.61
3	401	46	10	1.75
4	327	48	12	0.31
5	406	47	10	1.48
6	348	45	11	1.15
7	360	46	10	1.67
8	347	46	10	1.73
9	360	46	10	2.78
10	354	46	9	3.67
11	330	47	10	1.52
12	333	44	10	1.20
13	352	46	11	0.57
14	377	46	10	2.12

Note. For each slice, we show the total number of beads detected, their average radius, the dispersion of the radius values (standard deviation) and the percentage of false positives defined as the beads with radius larger than 5 the average.
