Retrieves the indices of the world axis physical types corresponding to a pixel axis.
Parameters
pixel_axis (int) – The pixel axis index/indices for which the world 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
world_axes – The world axis indices corresponding to the pixel axis.
