centroiding

This check-box determines if the source is to be centroided. If “checked” then the coordinates of each newly selected source will be refined by a centroiding algorithm. In some cases (eg a star near to a much brighter star) the centroiding algorithm may not work too well and it may be better to “uncheck” it.
