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?

    $\begingroup$ 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 How to Ask. :-) $\endgroup$ – Chappo Hasn't Forgotten Monica May 14 at 22:38
