CCL: Help with Mercury / defining a plane

A colleague of mine is using the program Mercury ( to define some planes in her crystal structure, and while it is doing what she wants, it is not reporting an error/sum of residuals (or any other uncertainty).  I know it is a long shot with this crowd, but does anyone have any experience with this?  Either a way to extract this information from the program, or another program that would allow us to define planes including some atom selections, and give residuals would be most appreciated.
