Emission Line Integration script failing

[twideman]

I'm running PI on a MacBook Pro under Catalina. Whenever I try to run the Emission Line Integration script, it cogitates a little, opens the script window, and starts dumping segmentation violations out the nose. None of the pulldowns work, and only the cancel button works. I've had this problem for a while (never used ELI before and have never gotten it to run) and I've updated PI and the repositories. I'd appreciate any thoughts on why I'm HaRGB challenged.

EmissionLineIntegration was frequently tested under Win10.
If you want, check out CS.
CS subtracts the continuum from a narrowband image. Then you can add the resulting image on your broadband channel using PixelMath with an optional amplification factor.
I.e: subtract R from your Halpha and run PixelMath on R with $T * a. Start with a = 1.
All this is integrated in EmissionLineIntegration for 3 channels. Using CS, you can add more channels step by step.

Hartmut,
Thanks for your reply. It's taken me a while to get back to trying to make it work.
Thanks for CS, I can at least hand-crank it out with PixelMath as you say.
I wish I knew why ELI was crashing out, it looks like a nice package, it's just not working on my platform.
Best,
Tom
