pixel_axis_to_world_axes

ndcube.utils.wcs.pixel_axis_to_world_axes(pixel_axis, axis_correlation_matrix)[source]

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.

Return type:

numpy.ndarray
