Talk:AB magnitude

Untitled

It would be good to mention what AB stands for (I have no clue -- hopefully not "ABsolute"). M. Tewes (talk) 08:57, 13 June 2012 (UTC)

I have not found no references to where that comes from. --JohannesBuchner (talk) 01:48, 20 November 2013 (UTC)

Wrong ecuation

I think that . $\,\!AB=-2.5\log _{10}f_{\lambda }-5\log _{10}(<\lambda >)-2.406$ it is not true in general. Verify it with this. http://stsdas.stsci.edu/Files/SynphotManual.pdf pag 29. Pmisson (talk) 19:47, 19 June 2013 (UTC)

Yes indeed, that is for a specific V-band filter. My edits should resolve this. --JohannesBuchner (talk) 22:14, 19 November 2013 (UTC)
