In the third display of our example the reference line (vertical line) is aligned according the
method *linear regression".
The max. error of the reference line is 2,0 µm.
The error of the second line is the maximum angular error of the whole object. Depending on the different
method of alignment this angular error may vary.
Maximum error related to reference line
 Alignment according to the method "ISO 1101"
 Alignment according to the method "Endpoints"
 Alignment according to the method "linear Regression"
