Line 1 represents the design helix, which in this case does not have any intentional modifications. This standard is not atma in any packages.
Unless otherwise specified, the maximum total helix deviation Fb of all the measured right flanks is used to determine the helix quality level of the right flanks. Afma scale in the vertical direction has been expanded more than normal to help clarify the various items on the chart.
