Best Fit Window
When best fit window is used, the specified window size (%) is shifted between the
threshold high and threshold low. The purpose is to find the best correlation between
the limits in order to plot the interpolation lines. As shown in the figure above,
variations in plotting the interpolation lines will affect the accuracy in predicting write
width, read width and read-write offsets.

finding the best correlation to plot the
interpolation lines.This value is expressed as
percentage between the high and low
threshold settings.
Specifies the maximum threshold value for
interpolation.
Specifies the minimum threshold value for
interpolation.
Specifies the starting point of the track offset
in building the track profile.This point is
defined as the distance in [µm] from the track
center.
