Sign error in the bin edges calculation in the definition in docs/shearstrain.ipynb ?

[opinner]

Bin edges are calculated as

depth_bin_edges = np.concatenate(
    (
        [np.min(depth_bin) - dz / 2],
        0.5 * (depth_bin[1:] + depth_bin[:-1]),
        [np.max(depth_bin) - dz / 2],
    )
)

This leads to an array of edges with the same last and second-to-last element.
Shouldn't it be:

depth_bin_edges = np.concatenate(
    (
        [np.min(depth_bin) - dz / 2],
        0.5 * (depth_bin[1:] + depth_bin[:-1]),
        [np.max(depth_bin) + dz / 2],
    )
)

with the sign changed in the last line?
