[vsnet-chat 7603] Re Ks band

[Martin Nicholson]

As the web page 

http://www.martin-nicholson.info/rainyday1/2massdenis.htm 

indicates the average (mean) difference between the 2MASS and 
DENIS K band magnitudes for the 25,000 stars studied was
0.0015.

If you find a star with about 1 magnitude difference then that
might be the *starting point* for a bit of fun.

Incidently the stars used were not close to the freely available
limiting magnitudes. This was *not by accident*.

The web page title "Variable Star Targets .." gives a good idea
of the scope of the project. There is no suggestion that these
are candidates for immediate submission into VSX.

I suspect John was well aware of all the above but no matter!
