Hi Steve,
Those are both nice spectra with clear atmospheric O2 absorption and stellar hydrogen absorption lines.
That is an interesting project to look for a change in the doppler shift. I do not know the velocity of the various components so can’t comment further on feasibility, but a great idea.
Cheers,
Andy
