- pyxem.utils.diffraction.reference_circle(coords, dimX, dimY, radius)[source]#
Draw the perimeter of an circle at a given position in the diffraction pattern (e.g. to provide a reference for finding the direct beam center).
- Parameters:
coords (numpy.ndarray size n,2) – size n,2 array of coordinates to draw the circle.
dimX (int) – first dimension of the diffraction pattern (size)
dimY (int) – second dimension of the diffraction pattern (size)
radius (int) – radius of the circle to be drawn
- Returns:
img – Array containing the circle at the position given in the coordinates.
