3-169 Laser Address Selection
• Point
This variable indicates the number of the selected point.
• Angle
This variable indicates the angular position (in degrees) of the selected point.
• Vert
This variable indicates the actual vertical position (in mils or mm, depending on
the analyzer units) of the selected point. The background for this variable will be
green for an active point and red for a deleted point.
• Est
This variable is the amplitude value of the sine fit curve at the particular angular
position.
Note
Although up to 180 data points can be acquired, not all the data
points are required for the fit calculation. However, a minimum of
three points is required to fit the data to the sine curve.
The following calculated sine curve variables are displayed at the bottom of the
screen:
• Phase
This variable indicates (in degrees) where the plus zero transition is positioned.
• Offset
This variable indicates (in mils or mm, depending on the analyzer units) the cen-
terline of the laser travel on the target in the radial direction. The initial position of
the laser on the target affects this variable.
• Amplitude
This variable indicates the maximum displacement (in mils or mm, depending on
the analyzer units) of the sine curve from the offset line.
• Correlation
This variable indicates the confidence factor (shown as a percentage) used to deter-
mine the quality of the sine curve data. In other words, it indicates how well the
points fit the sine curve.
