A new format for the residual - distortion, called ``NPOL`` files (extension ``_npl.fits``), is presented in this document. - The conversion from ``DGEO`` files to ``NPOL`` files is described and an example of the format is given - using ACS/WFC F606W filter. Tests of the conversion procedure show that the - differences between the ``DGEO`` files and ``NPOL`` files are of the order of :math:`10^{-4}` - pixels. - Introduction ============ -- cgit
