Re: [ferret_users] Interpolation 2D issue

Hi Szymon,
The scat2gridgauss_xy function has arguments which determine how far the 
algorithm looks in the data to place it into the output grid.  It would 
not normally be used for a regridding operation but there's nothing 
wrong with trying it of course.
