   .. attribute:: N <int>

      The bandwidth :math:`N \epsilon N_0`. Must be a positive integer.

   .. attribute:: M <int>

      The number of nodes. Must be a positive integer.

   .. attribute:: flags <ctypes.c_uint32>

      The NFSFT flags.

   .. attribute:: nfft_flags <ctypes.c_unit32>

      The NFFT flags.

   .. attribute:: nfft_cutoff <int>

      The NFFT cutoff.

   .. attribute:: x <numpy.ndarray>

      Float array for sampling nodes.

   .. attribute:: f <numpy.ndarray>

      Complex array for NFSFT values or coefficients for the adjoint NFSFT.

   .. attribute:: fhat <numpy.ndarray>

      Complex array of spherical Fourier coefficients for the NFSFT or values for the adjoint NFSFT.

   .. attribute:: init_done <boolean>

      Boolean to indicate if the NFSFT plan is initialized.

   .. attribute:: finalized <boolean>

      Boolean to indicate if the NFSFT plan is finalized.
