CH Cyg not too sure about shape?

[SteveCuthbert]

Hi guys
I took this one of CH Cyg the other evening and wondering if I`ve got the shape correct ?. No instrument response has been done and this is just what ISIS came up with.
Other plots of CH Cyg I`ve seen show the intensity rising towards the red!.

Hello Steve,

The emission lines are impressive !
All seems correct, unless the continuum of the M giant, as you note.
You can't get a good continuum if you don't compute an atmopsheric/intrumental response with a reference star.
All the best,
François
