Basic Information on impoly
Purpose: Flat field subtraction using a 2D polynomial fit
Categories: map combination
IMPOLY (IMage POLYnomial subtraction) is a MIRIAD task that
performs a least squares polynomial fit to a specified region
of each plane of a cube and subtracts this fit from the entire
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. Note: the coefficients are defined w.r.t. the
reference pixel, and are in pixel units. Default is not.
Full region specifications are supported. Defaults to the
