FIELD_LIST

        FIELD_LIST

    This  task computes statistics on fields of an image.  It accepts as in-
    put  the  image  itself  and a label image describing the  fields.   The
    label image is an image (of same size as the input image), in which  the
    value of a pixel is the number of the field to which it belongs.  A zero
    value is attributed to pixels which do not belong  to  any  field.   The
    label image is usually obtained by running task FIELD_FIND.

         The output is a Table file containing :
    Col 1 Number of pixels
    Col 2 Integrated flux
    Col 3 X Abscissa of centroid ( i.e., Weighted by pixels value)
    Col 4 Y Ordinate of centroid ( idem)
    Col 5 Major axis of fitted ellipsis       (should be correct now)
    Col 6 Minor axis of fitted ellipsis       (idem)
    Col 7 Position angle of fitted ellipsis   (idem)
