dZ_dx

mmtwfs.zernike.dZ_dx(m, n, rho, phi, norm=False)

Calculate the X slopes of Zernike mode (m, n) on grid rho and phi.

Parameters

mint

m-th azimuthal Zernike index

nint

n-th radial Zernike index

rho2D ndarray

Radial coordinate grid

phi2D ndarray

Azimuthal coordinate grid

normbool (default: False)

Normalize modes to unit variance (i.e. Noll coefficients)

Returns

dwf2D ndarray

Wavefront slope in X described by Zernike mode (m, n). Same shape as rho and phi.
