ARGUMENTS
.ls asi

DESCRIPTION
ASIGETR is used to set the value of undefined drizzle interpolant pixels.
Undefined pixels are those for which the interpolation coordinates do not
overlap the input coordinates, but are still, within the boundaries of the input
image, a situation which may occur when the pixel fraction is < 1.0.
