```

ds.sel(lat=[5,15,40], method="nearest", tolerance=5) <xarray.DataArray (lat: 2)> array([1, 2]) Coordinates: * lat (lat) int64 10 20 ```

This is a very surprising result, you've asked for values at three points but received two back.

The following (specifying fill_value) seems like better behaviour to me but how do you choose the coordinate label (here I picked 40 since that was provided to sel) ```

ds.sel(lat=[5,15,40], method="nearest", tolerance=5, fill_value=-999) <xarray.DataArray (lat: 2)> array([1, 2, -999]) Coordinates: * lat (lat) int64 10 20 40 ```
