I've begun doing my data reduction with Demetra for spectra obtained with an Alpy 600. How could I get sequential profiles of the same star taken on different days, on one page, so that I could compare changes is the spectra?
Hi Dick,
You can plot a sequence of spectra using Valerie Desnoux VisualSpec for example
http://astrosurf.com/vdesnoux/
but for high quality plots I use Tim Lester's PlotSpectra

Cheers

Dick,
As well as the above, BASS Project will do that for you.
