world_axis_to_pixel_axes#

ndcube.utils.wcs.world_axis_to_pixel_axes(world_axis, axis_correlation_matrix)[source]#

Gets the pixel axis indices corresponding to the index of a world axis.

Parameters:

world_axis (int) – The index of the physical type for which the pixels 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.wcsapi.BaseLowLevelWCS.axis_correlation_matrix.

Returns:

pixel_axes (numpy.ndarray) – The pixel axis indices corresponding to the world axis.
