A particularity of HDF datasets
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
When reading a HDF dataset, one needs to select the right subdataset
using the :doc:`Extended filenames` ``&sdataidx=<(int)idx>``. For
example, in some COsmoSkyMed products, the first subDataset is a
quicklook, and the actual product is the second subdataset.
