Supplemental Figure 1 duplicate of cover image diameters:
Count, N: 45
Sum, Sx: 8062.005
Mean, µ: 179.1556667 + 11.68
Variance, s2: 136.5137976

signif diff to 0.00001 cover image reduction should be 74.2%
purpose: to use the LUT plots from cover images and Sup Fig 4 i images (of which there were 15 duplicates that i used) to add data in replicate.

All together the cover and supp fig 4 measurements (3 per dodecamer) leaves the diameter at: for this AFM image.
