New "constant" kernel?

Dear ISIS users

	Thanks for fixing that bug so quickly! I was wondering how easy it
would be to add another kernel to ISIS that would behave like the
XSPEC "constant" model -- for example set_kernel(3,"constant") would
multiply the model as applied to data set 3 by some constant value.
Then multiple data sets could be fit simultaneously with different
normalizations. The reason I ask is that we're interested in
simultaneously fitting slightly piled-up Chandra data and RXTE data,
the normalizations of which differ. I'd guess that writing such a
kernel would be considerably easier than changing the way ISIS
applies models to different data sets? I don't suppose anyone has
plans to code up such a kernel in the near future...?

Many thanks
Andy Young

PS Sorry if I'm repeating anything you've discussed recently but
because of a computer problem I lost some emails from the ISIS
list...
