FIELD_LIST
This task computes statistics on fields of an image. It accepts as
input 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)
