How should we understand curved facets?

Babkin et al have found a small curvature in facets of4He crystals. As a possible explanation they consider a model where the curvature arises from thermally activated defects previously studied by Andreev. We criticize this model, and suggest that the curving arises from pinning of steps near the facet edge.
