Currently only mass and phasespace coordinates are converted. This is still done in code units, in a future option conversion to astrophysical units will be possible.
debug=1 will also list the datasets contents of the HDF5 file.

Objects near the edge, may seem to wind up in two places, as can be seen in the following example snapshot:

RefL0012N0188 is the small volume (12Mpc) reference run. It has 29 slices in z, ranging from slice 0 at z=20 to slice 28 at z=0.0. Slice 27, the one but most recent slice, is at z=0.10. The number of particles is (188^3) 6,644,672 per species (gas and DM). At z=0 one can see 6,381,559 gas, 262380 stars, and 547 BH, this still 186 short, so did some merge? This means SFE = 4.0% Each snapshot comes in "nfiles" parts, e.g. snap_028_z000p000.0.hdf5, snap_028_z000p000.1.hdf5, ... snap_028_z000p000.15.hdf5. The read_eagle routines will automatically read of all these in order to populate the snapshot correctly.
Simulations with L=12, 25, 50, 100 co-moving Mpc are available.
