A gadget data file must at least contain positions, velocities, keys (ids), masses (if not specified via the header), and internal gas energies. In addition it may contain gas densities, gas smoothing lengths, potentials, and accelerations. All data specified by the IOstring will be written, but at least mxvkU and at most mxvkURHap. If some data were not present in the nemo snapshot, zero values will be substituted.
