*Meaning of Each Column
 First  column: frequency                         [Hz]
 Second column: real part of spring constant      [N/m]
 Third  column: imaginary part of spring constant [N/m]

*Axes
 x: Horizontal longitudinal axis to the heat link
 y: Horizontal transversal axis to the heat link
 z: Vertical axis
