Returns one of the following descriptions, corresponding to the
passed-in short curve fit name.
calculates a single parameter least squares fit. The
Linear
equation is in the form: y = Ax + B. It is commonly used for
dispersion-shifted fiber, in which waveguide dispersion is
dominant.
calculates a second order polynomial fit. The
Quadratic
equation is in the form:
2
y = Ax + Bx + C .
3rd Order Sellmeier
unshifted fiber, in which material dispersion is dominant.
The equation is in the form:
2 -2
y = A + B + Cx
