V-I Color Index and Astronomical Catalog

  1. Nov 26, 2007 #1
    Well, this is awkward.

    I seem to have forgotten what star has a 0.0 value in the V-I color index. I almost want to say Vega but that's the 0.0 in the B-V color index.

    I also seem unable to find raw data for the V-I color index values for spiral galaxies and was wondering if someone would be willing to assist.

    If you have any questions, feel free to post. I also wanted to start a conversation in posting.

    I think your best bet would be to search for papers by Mike Bessell on http://adsabs.harvard.edu/abstract_service.html" [Broken] abstract server. He was a pioneer in standardising photometric systems. Failing that, try looking for papers by Cousins from the late 70/early 80s.

    I would totally kid you for giving a responce that didn't lend itself to discussion, but I lost this link months ago and had been looking for it.

    I wish I could give high fives/respect knuckles over the internet.
