# xarray.core.indexing.OuterIndexer

### *class* xarray.core.indexing.OuterIndexer(key)[[source]](https://github.com/pydata/xarray/blob/main/xarray/core/indexing.py#L509-L550)

Tuple for outer/orthogonal indexing.

All elements should be int, slice or 1-dimensional np.ndarray objects with
an integer dtype. Indexing is applied independently along each axis, and
axes indexed with an integer are dropped from the result. This type of
indexing works like MATLAB/Fortran.
