Circle of Least Confusion, the precise figure used in further calculations when a range is available. How do you calculate it?

I don't but could.

I would need to do more rays than are shown here and report the maximum value; right?

Extreme close-up of on-axis rays near the image plane

I think of that as Transverse Spherical Aberration (TSA) see Spherical aberration

I could probably report Lateral Spherical Aberration (LSA) as well.
