DESCRIPTION
IMPOLY (IMage POLYnomial subtraction) is a MIRIAD task which
performs a polynomial least squares fit to a specified
xy region of each plane of a cube and subtracts this
fit from the entire plane.
PARAMETERS
 in

The input image. No default.
 out

The output image. No default.
 order

The degree of the highest term of the polynomial fit.
It is not possible to have a different order of the polynomial
in X and Y. Default is zero (i.e. fit a constant).
 coeffs

A logical, specifying whether you want to see fitted polynomial
coefficients. Default: no.
Note: the coefficients are defined w.r.t. the reference pixel,
and are in pixel units.
 region

Full region specifications are supported.
Default: the entire image.
