impoly - Flat field subtraction using a 2D polynomial fit
IMPOLY (IMage POLYnomial subtraction) is a MIRIAD task which
performs a polynomial least squares fit to a specified
x-y region of each plane of a cube and subtracts this
fit from the entire plane.
The input image. No default.
The output image. No default.
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).
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.
Full region specifications are supported.
Default: the entire image.
