Main Question or Discussion Point

Dear all

Please find the attached picture. I have a question on Dimensionless radius.
I believe that it is a ratio of radius and maximum radius . The range should be 0-1 . But in the attachment I found that in the x axis the range is 0- 3 . Can you please explain how?

Thank you

It is the radius divided by some reference value. That can be the maximal radius, but it does not have to be. Apparently, in this graph it is not the maximal radius, it looks more like a typical radius.
