Methods Documentation

array_index_to_world(*index_arrays)

Convert array indices to world coordinates (represented by Astropy objects).

See array_index_to_world_values for pixel indexing and ordering conventions.

pixel_to_world(*pixel_arrays)

Convert pixel coordinates to world coordinates (represented by high-level objects).

See pixel_to_world_values for pixel indexing and ordering conventions.

world_to_array_index(*world_objects)

Convert world coordinates (represented by Astropy objects) to array indices.

See world_to_array_index_values for pixel indexing and ordering conventions. The indices should be returned as rounded integers.

world_to_pixel(*world_objects)

Convert world coordinates (represented by Astropy objects) to pixel coordinates.

See world_to_pixel_values for pixel indexing and ordering conventions.
