RESULTS OF ROTATIONAL STABILITY ANALYSIS
Results in the tables below represent critical circles identified between specified points on entry and exit. (meta-exit set to 50.00 deg.)
The most critical circle is obtained from a search considering all the combinations of input entry and exit points.
Crltlcal circles for each entry point (considering all specified exit points)

Note: In the 'Status' column, OK means the critical circle was identified within the specified search domain. 'On extreme X-entry means
that the critical result is on the edge of the search domain; a lower Fs may result if the search domain is expanded
