One sigma is 66%
Two sigma is 95%

In Ashtech Solutions, vectors "Pass" or "Fail" is entirely subjective. Depends on user set up preferences in settings. YOU can determine where vectors pass or fail in the QA, whether one sigma or two sigma. It's relative to whether you ask the software to evaluate the statistical values relative to the diameter of a dime, or to a washtub.
