Simulated Asymmetry with radial dependence

Calculated a radial dependence from data as a fit line of a graph that shows asymmetry versus the radial position as one of three rings.  Then used this to generate simulated data that would adjust asymmetry based on radial position.  It yielded the below asymmetries which are some what strange in that there were no luminosity or geometry asymmetries before introducing this and now there clearly are.  I need to look into this further and see if I cannot resolve the issue.
