[vsnet-chat 6272] Re: color conversion

Dear colleagues,

Does anyone know a web page which shows a color conversion diagram or
formula between 2MASS JHKs color and UBVRI color, or GSC2 JFN color
and UBVRI color?

For example, a diagram between 2MASS J-Ks and Johnson B-V, or between
GSC2 J-F and Johnson B-V.

On 2MASS color, I know the page:

  http://ftp.lowell.edu/pub/bas/starcats/uvby.calib

is helpful. But I would like to see a diagram or conversion formula,
too, if exists.

On GSC2 color, I found "gsc2_johnson_kron_cousins.txt" in GOOGLE
cache, but the original file is now not found...

Thanks in advance,

Seiichi:
I have a few conversion formulas on http://members.aol.com/dwest61506/page53.html. Click on "Photometric Conversion Formulas".  I may have some of what you need.

Doug West
