Where do Astronomers usually get their wavelengths? Where do they turn to look up standard, accepted values for spectral features?
When identifying isolated observed spectral features or fitting complex observed spectra or even running complex numerical simulations, one needs a reliable, standard table of known wavelengths and ...

Spectral analysis of AGN (velocity dispersion of galaxy absorption, doppler shifts)
I was wondering what parameters I need to know/measure to calculate the velocity dispersion of a galaxy, specifically an AGN.
Also, I have spectra where there are blueshifted and redshifted ...
