Background Page (Star Removal)
Settings on the Background page affect the background subtraction and the color of the markers. Any option on this page results in all targets and templates being re-evaluated on all images.

Background Method |
Select from this list the order of polynomial to fit to pixels in the background region around each object. The background is evaluated between the Middle Aperture and Outer Aperture of the marker. This affects both template samples and target objects. A 2x2 polynomial is usually a good choice since it can accommodate a constant, sloped, or twisted surface underneath the star. |
