    65  To see the actual points selected by the program, click on the "show ring picks?" check button. When this is done, it becomes clear that the points selected for the outermost ring are scattered between that and the next ring. This can be repaired by using the Image Operations/Clear Calibration menu item, lowering the area the program uses for searching for points by changing the "pixel search range" to 10 and then repeating the calibration steps (selecting points again on the first ring and then using the right mouse button.) This produces very slightly better calibration constants.
