Gets the pixel axis indices corresponding to the index of a world axis physical type.
Parameters
world_axis (int) – The index of the physical type for which the pixes axes are desired.
axis_correlation_matrix (numpy.ndarray of bool) – 2D boolean correlation matrix defining the dependence between the pixel and world axes.
Format same as astropy.wcs.BaseLowLevelWCS.axis_correlation_matrix.
Returns
pixel_axes – The pixel axis indices corresponding to the world axis.
