Level 2 core flow.

Parameters:

  • data_list (list[str] | list[NDCube]) – The files or data cubes to be merged into a mosaic

  • voter_filenames (list[list[str]]) – The voter files for detecting bright structures

  • polarized (bool) – Whether to generate a polarized or clear mosaic. Only required if data_list is not provided (and so an empty cube is being generated). Otherwise, this is auto-detected.

  • trefoil_wcs (WCS | None) – The frame to build the mosaic in. By default, the default trefoil mosaic is used.

  • trefoil_shape (tuple[int, int] | None) – The size of the frame to build the mosaic in. By default, the default trefoil size is used.

  • trim_edges_px (int) – Before reprojection, image edges are trimmed by this amount, and the masked region is expanded by this amount.

  • alphas_file (str) – File path containing alpha scalings for relative instrument scaling.

  • output_filename (str | None) – If provided, the resulting mosaic is written to this path.

Returns:

output_data – The resulting data cube. For compatibility, it will be a list of a single cube.

Return type:

list[NDCube]
