[Users] Simulation tools' problem in loading binary data

It appears that your BH_diagnostics.ah2.gp file is missing a single
iteration (41440). My guess would be that this is because the apparent
horizon finder failed to find a horizon at this iteration.
This causes trouble when trying to combine the two individual puncture
trajectories into a single separation vector. Perhaps SimulationTools
should somehow be more tolerant of this scenario, although my test shows to
enabling resampling works around it. Alternatively, you can just work with
the individual puncture trajectories with something like the following:
(* Read individual trajectories *)
traj1 = ReadBinaryCoordinates["test", 1];
traj2 = ReadBinaryCoordinates["test", 2];
(* Cut out the bad bit at the end *)
traj1 = Slab[#, 0 ;; 121.312] & /@ traj1;
traj2 = Slab[#, 0 ;; 121.312] & /@ traj2;
(* Compute coordinate separation *)
sep = Norm[traj1 - traj2];
I hope this helps,
