ndcube.utils Package

ndcube.utils.cube Module

Utilities for ndcube.

Functions

wcs_axis_to_data_axis(wcs_axis, missing_axes)	Converts a wcs axis number to the corresponding data axis number.
data_axis_to_wcs_axis(data_axis, missing_axes)	Converts a data axis number to the corresponding wcs axis number.
select_order(axtypes)	Returns indices of the correct data order axis priority given a list of WCS CTYPEs.
convert_extra_coords_dict_to_input_format(…)	Converts NDCube.extra_coords attribute to format required as input for new NDCube.
get_axis_number_from_axis_name(axis_name, …)	Returns axis number (numpy ordering) given a substring unique to a world axis type string.

ndcube.utils.sequence Module

Utilities for ndcube sequence.

Functions

slice_sequence(cubesequence, item)	Slice an NDCubeSequence given a slicing/index item.
convert_item_to_sequence_items() ))	Converts NDCubeSequence __getitem__ item to list of SequenceSlice objects.
convert_cube_like_item_to_sequence_items(…)	Converts an input item to NDCubeSequence.index_as_cube to a list od SequenceSlice objects.
convert_slice_nones_to_ints(slice_item, …)	Converts None types within a slice to the appropriate ints based on object to be sliced.

Classes
