A Table defines a transformation to be applied to an independent variable to produce a dependent variable. A Table contains an optional list of offsets and a list of point-pairs ( x, y ) used in the transformation. x refers to the independent variable and y refers to the dependent variable. The dependent variable is computed by first applying any defined Offsets to the independent variable and then determining a value using interpolation between enclosing point-pairs. The sequence number of a curve point. The independent value of a curve point pair. The dependent value of a curve point pair.
