classmethod FourierZernikeProfile.from_values(r, t, z, f, L=6, M=0, N=0, NFP=1, w=None, name='')Source

Fit a FourierZernikeProfile from point data.

Parameters:

• r (array-like, shape(k,)) – coordinate locations in rho, theta, zeta

• t (array-like, shape(k,)) – coordinate locations in rho, theta, zeta

• z (array-like, shape(k,)) – coordinate locations in rho, theta, zeta

• f (array-like, shape(k,)) – function values

• L (int) – maximum mode numbers to fit

• M (int) – maximum mode numbers to fit

• N (int) – maximum mode numbers to fit

• NFP (int) – number of field periods

• w (array-like, shape(k,)) – Weights to apply to the y-coordinates of the sample points. For gaussian uncertainties, use 1/sigma (not 1/sigma**2).

• name (str) – name of the profile

Returns:

profile (PowerSeriesProfile) – profile in power series basis fit to given data.
