I have 42 rows.
Problem is that I did not got all relative ellipses.
For most directions, these is missing relative confidence info.
You can not specify one point twice. For example, if you have specified S1 - S2, S1 - S3 will be ignored. Please note that the procedure is part of a deformation analysis and it is not usually useful to check whether the point S1 is congruent to S2 AND S3. So, you have to restrict the point nexuses.
