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
ofbool
) – 2D boolean correlation matrix defining the dependence between the pixel and world axes. Format same asastropy.wcs.BaseLowLevelWCS.axis_correlation_matrix
.
- Returns
world_axes – The world axis indices corresponding to the pixel axis.
- Return type
numpy.ndarray
