hi Vinay,
no f_sar is a function. It is an array filled with numbers. If you mean by
SAR cycles the start and end points of the green and red dots you can find
them using the Cross function as well. Add this to the code and you will
find that a "1" is printed at the start and end of the "cycles", rgds, Ed
SAR_cycle_start = Cross(C,f_sar) OR Cross(f_sar,C);
"start: " + WriteVal(SAR_cycle_start);
SAR_cycle_end = Ref(SAR_cycle_start,1);
"end: " + WriteVal(SAR_cycle_end);
