[vsnet-chat 3533] Re: V-I to B-V sums...

[Brian Skiff <bas@lowell.edu>]

     Until you get to around K5/M0, B-V and V-I have similar values.  Redder
than that, B-V stays roughly constant, while V-I keeps increasing.
     The best color-to-color conversions are those of Caldwell et al., which
were published in the SAAO Circulars, no. 15, page 1 (1993).  They are 
complicated polynomials, and I have several of them for BVRI colors in 
FORTRAN code if that helps.  Write me separately if you want them.
