calculate_master_pattern#

KikuchiPatternSimulator.calculate_master_pattern(half_size: int | None = 500, hemisphere: str | None = 'upper', scaling: str | None = 'linear') → EBSDMasterPattern[source]#

Calculate a kinematical master pattern in the stereographic projection.

Requires that the reflectors have structure factors (structure_factor) and Bragg angles (theta) calculated.

Parameters:

half_size: Number of pixels along the x-direction of the square master pattern. Default is 500. The full size will be 2 * half_size + 1, given a master pattern of shape (1001, 1001) for the default value.
hemisphere: Which hemisphere(s) to calculate. Options are "upper" (default), "lower" or "both".
scaling: Intensity scaling of the band kinematical intensities, either "linear" (default), \(|F|\), "square", \(|F|^2\), or "None", giving all bands an intensity of 1.

Returns:

master_pattern: Kinematical master pattern in the stereographic projection.

Notes

The algorithm for selecting which unit vector is within a Kikuchi band is derived from a similar routine in EMsoft.
