Recently I added the option to compute InspiralRange in Pastavi. The computed result is consistent with Yamamot-san's one, Tagoshi-san's one, and my independent code.

I expaneded this to compute the mass-range plot. (I don't know the proper name.) 

Anyway, try to plot "mass range plot" on Pastavi.

If you found the bug or the error, please let me know. Thank you.

If you have any comment, please let me know.
