Try to insert just before plot(...) the following two lines:
igc=np.sign(ig_bdry-ig_d2) ig_d2[igc!=igc[1] ]=np.nan This [1] is a place which discriminates where the difference sign is "good". Of course this will produce some bedlam if there are many intersections. You didn't say whether you want to plot the dashed curve entirely. If not, just truncate all three, the solid, the dashed and the abscissa, where the sign is OK. Good luck.
