Hello Lalehan,
a.u. stands for "arbitrary units".
The rmsd-dist contains a histogram over the distribution of rmsd
values, you can read the a.u. as counts per length-interval.
I would suggest that all histograms that GROMACS produces actually be
labeled reasonably in the code - using a.u. is itself arbitrary because
it has multiple possible meanings. If it's a raw histogram, we should be
using "Frequency" and if normalized, "Probability."
