zernike_slope_noll

mmtwfs.zernike.zernike_slope_noll(j, rho, phi, norm=False, cache=None)[source]

Calculate X/Y slopes for Noll Zernike mode j on grid rho and phi. rho and phi must be radial and azimuthal coordinate grids of identical shape, respectively.

Parameters:

jint: j-th Noll Zernike index
rhondarray: Radial coordinate grid
phindarray: Azimuthal coordinate grid
normbool (default: True): Normalize modes to unit variance (i.e. Noll coefficients)

Returns:

dwx, dwx2D ndarray, 2D ndarray: X/Y wavefront slopes of Noll Zernike mode, j. Same shapes as rho and phi.
