Re: (fwd) to V or not to V - I couldn't resist it

   In unfiltered CCD photometry, no special conversions are necessary for
CVs (particularly disk-dominated objects) having colors close to B-V=0.
Selecting a blue comparison star, the color effect is in most cases mininal.
In very special cases, we need to correct secondary color terms.
