• Star Removal package: Added a Centroid Target Star checkbox to the Marker Properties page in the Star Removal Properties dialog. If the target star being removed is isolated from overlapping star profiles, the best results are obtained by checking Centroid Target Star. This option calculates an accurate centroid position for the intensity-weighted light profile near where you click the mouse. However, if the target star has an overlapping light profile from a nearby star, the contaminating light profile can cause the centroid position to shift away from the actual location of the target star. The workaround for overlapping profiles is to manually place the target location without centroiding. To disable target centroiding, uncheck this checkbox. To return to centroiding the target star, go back to the Marker Properties page and re-check this box.
  NOTE: The Marker Properties page also has a Centroid checkbox that controls the positioning of template stars, and it is usually desirable to build the master template by centroiding on isolated template stars.
