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
