    848 '''PATCH1: ''' interpolates the velocity values on a regular grid with a smoothing effect controlled by the parameter '''[num_!FieldSmooth]'''. The interpolation relies on the thin plate spline method, see [#tps: section 5.1]. This also provides the spatial derivatives (vorticity, divergence) needed for the refined processing civ2 (with option 'deformation').

    850850The vectors which are too far from the smoothed field (erratic vectors) are eliminated (marked by an error flag), using a threshold set by '''[num_!MaxDiff]''' (expressed in pixel displacement). The interpolation is performed again by the program after this elimination.
