How tolerances are calculated
For each point of the
profile, the sigma is
calculated. the toler-
ance point are calcu-
lated with the
following statistical
formula:
Average +/- X sigma
By default X = 3 to enlarge tolerances (This value can be changed in the .ini file.
If this value increased, tolerances are larger).
The same principle is apply to calculate the limit of the
Expert mode
algorithm.
