Dear Paul,
that’s a fantastic example in order to use it in my regular spectroscopic seminars at the University of the city of Wuppertal here. Mostly seminars for beginners. Is it possible to get the fits file?
I would like to scan the sky and the spectrum separately in order to show the emissions of the sky within the spectra itself and how important the subtraction is.

Best wishes, Ernst
