Elena, your question has been flagged for closure because it lacks sufficient detail to clarify the problem. Adding a further explanation *in a comment* isn't enough, since the assessment is made on the question itself. I'll add the information you've provided (and fix the spelling/grammar issues), but "which database should I use" invites subjective opinion, which is also a reason for closure. Can you [edit] your post to provide greater focus, e.g. what you will use the data for? If possible, try also to rephrase your question so that there's a *definitive answer*. See also [ask]. :-)

Thank you very much and how to find spectra there?

I am searching all available spectroscopic data (and particularly wavelength interval) of 28 CMa in the constellation Canis Majoris to measure radial velocities. Which database should I use?
