lsf

Returns amplitudes (C) and phases (pha) of the harmonic components of series,

i*cos(2*pi*t/Ti-phai).

For imaginary series, the amplitudes and phases of the real and imaginary part is converted in ellipse parameters semi-major and minor axis, inclination and phase angle).

In the screenshot is shown two outputs, for real and imaginary series (see the examples on the file).

The output of this function has the same form of T_TIDE output so it can be used by other T_TIDE utilities.
