ptypy.utils.scripts.stxm_analysis#

ptypy.utils.scripts.stxm_analysis(storage, probe=None)#

Performs a stxm analysis on a storage using the pods.

This function is MPI compatible.

Parameters:

  • storage (ptypy.core.Storage instance) – A Storage instance to be analysed

  • probe (None, scalar or array) –

    • If None, picks a probe from the first view’s pod

    • If scalar, uses a Gaussian with probe as standard deviation

    • Else: attempts to use passed value directly as 2d-probe

Returns:

  • trans (ndarray) – Transmission of shape storage.shape.

  • dpc_row (ndarray) – Differential phase contrast along row-coordinates, i.e. vertical direction (y-direction) of shape storage.shape.

  • dpc_col (ndarray) – Differential phase contrast along column-coordinates, i.e. horizontal direction (x-direction) of shape storage.shape.
