Looks to me like r_min is set to  r_min = 2 *
self.pf.h.get_smallest_dx() * self.pf['mpc'], or thereabouts, from
line 355 in yt/analysis_modules/halo_profiler/multi_halo_profiler.py.
So it's grabbing a profile and setting the inner bin to that.  The
point on which it's centered is also not included, because you're
asking for a log-spaced profile, and the log of 0 is a NaN.

So I guess the next question is, given these constraints, is it
behaving as you'd expect?
