• The centroid will be meaningless if the region does not contain a point like source.
• The format and name of the quality and error data have not been agreed yet.
• The region selection should be carried out by first unfurling the image in a pseudo event list, then making a call to evselect (there will be an f90-callable interface), then computing the relevant statistics on the filtered pseudo event list.
