  • $\begingroup$ For me the first code seems to work fine, where the srgData[[1]] is the resulting table. The second could be midfield to data = Reap[ ParametricPlot[{Sow[{Re[k[w]], Im[k[w]]}]}, {w, -Pi, 0}, PlotRange -> {{-0.7, 2.1}, {0, 1.1}}]] and then data[[2,1]] is the table. $\endgroup$ Commented Jun 16, 2021 at 14:32
  • $\begingroup$ Apologies @Moo, I've edited it to fix that. $\endgroup$ Commented Jun 16, 2021 at 15:05
  • $\begingroup$ @Andrzej, you are right. It works fine. It seems that in constructing a MWE, I've accidentally made it work... looking into it now $\endgroup$ Commented Jun 16, 2021 at 15:13

    $\begingroup$ Why not just generate a table of points? p = Table[{w, Re[k[w]], Im[k[w]]}, {w, -Pi, 0, Pi/500}]; p = Select[p, 0 <= #[[3]] <= 1.1 && -0.7 <= #[[2]] <= 2.1 &]; I know the "spacing" of the points is nicer with ParametricPlot but does that really matter for what you want to do? $\endgroup$ Commented Jun 16, 2021 at 15:23
  • $\begingroup$ I agree with Jim, especially if you're a beginner. Why not use something clean, robust and simple instead of a fragile hack? $\endgroup$ Commented Jun 16, 2021 at 15:39
