azimuthal_integrate1d

pyxem.utils.diffraction.azimuthal_integrate1d(z, azimuthal_integrator, npt_rad, mask=None, sum=False, **kwargs)

Calculate the azimuthal integral of z around a determined origin.

This method is used for signals where the origin is constant, compared to azimuthal_integrate which is used when the origin in the data changes and is iterated over.

Parameters:

• z (numpy.ndarray) – Two-dimensional data array containing the signal.

• azimuthal_integrator (pyFAI.azimuthal_integrator.AzimuthalIntegrator object) – An AzimuthalIntegrator that is already initialised and used to calculate the integral.

• npt_rad – The number of radial points to integrate

• mask (Boolean Array) – A boolean array with pixels to ignore

• sum (bool) – Returns the integrated intensity rather than the mean.

• **kwargs – Keyword arguments to be passed to ai.integrate2d

Returns:

• tth (numpy.ndarray) – One-dimensional scattering vector axis of z.

• I (numpy.ndarray) – One-dimensional azimuthal integral of z.
