Vertex-centred AMR data?

I have implemented a front-end for cell-centred Cactus AMR data. However,
many Cactus simulations use vertex-centred AMR. That is, data is stored at
the vertices of a grid (not in the cells), and coarse vertices are at the
same locations as fine vertices.
How do I present such data to yt? Do I need to set grid coordinates
differently, or is there a "vertex centred" flag?
When vertex-centred data are displayed, then I expect either a "control
volume" around each vertex to have the same value, or to use e.g. linear
interpolation in the cells from the respective boundaries.
