If your bands are too narrow, you may fall foul of significant aliasing errors, i.e. having a non-negligble number of pixels counted in more than one band.
> Convert each circle to a band one pixel wide and measure.

> Hello, I was wondering if anyone could help me figure out a way to take the average pixel intensity along a high number of concentric circles (~100).

> I know the Concentric Circle plugin will let me overlay concentric circles on the image... but is there anyway to get the average intensity along/around the perimeter of each of these circles?
