integrate_radially

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

Calculate the radial integrated profile curve as I = f(chi)

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 (int) – The number of points in the output pattern

• npt_rad (int) – The number of points in the radial space. Too few points may lead to huge rounding errors.

• 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.
