Hello,
I am currently a student. I found a job at my university and I must do some spectroscopy. My director haven`t done any spectroscopy for years so he cannot answer any of my questions! =(I read a lot and I think I got to the point where I must do a flux calibration.
( I got the wavelength calibration).
I got many standard stars, their magnetude and their spectral type.
For exemple, 29 Vul, A0 Va(shell), V=4.82
RY Tau, K1 IV-V, V=10.01
61 Cyg, K7 V, V=6.03and many more.
The thing is that I read that the task standard use files already in IRAF that contains stars...
I`ve done page onedstds&README to check it out...but none seems to have the same name of my standard stars...It seems I also need the airmass which my director didn`t give me...Anyway...Anyone can help me out on this? What are the step I need to follow? Do I use the files already included in IRAF?

I dont remember much for spec reduction, but you can always use secZ for airmass, look in the headers.
Cheers! / Saludos!
