Task: 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 plane. Key: in The input image. No default. Key: out The output image. No default. Key: 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). Key: coeffs 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. Key: region Full region specifications are supported. Defaults to the entire image. Revision: 1.5, 2013/08/30 01:49:21 UTC
