Hi,
The missing pixels are in a groups so I can not do so.
For now I'm using the MPFIT2DFUN.PRO (Craig's code
http://www.physics.wisc.edu/~craigm/idl/idl.html)

I'm using a binary mask for the WEIGHTS, but the result is not smooth
at all.
If I take the missing edge then I must to keep the fit function (f) to
be also fit on the 2D gradient function (df/dx and df/dy) on the
bounds.
Can I add these rules to the MPFIT2DFUN ?
