This command calculates the average point from a selection of input points and reports the residual statistics. The input points can be specified by point number, by point group or by screen selection. The program displays the input points with residuals in a dialog where you can toggle on/off whether to include points in the average using the Process On/Off button. The Remove button removes a point from the average and the residual report. There is an option whether to output the average point to the current coordinate file. The option to delete all the input points applies when there are several points that are meant to be the same point and you want to replace them with a single averaged point. The command shows a report of the input points, residuals and average point.
