RESULTS OF ROTATIONAL STAR11-11Y ANALYSIS
Results in the tables below represent critical circles identified between specified points on entry and exit. (Theta-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.
Critical circles for each exit point (considering all specified entry points)

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