Hi,

While running HaloProfiler, I am seeing this...

P001 yt.lagos   ERROR      2009-12-08 15:53:22,403 Skipping halo with r_max / r_min = 1.885682.



I looked at yt/extensions/HaloProfiler.py...

           r_min = 2 * self.pf.h.get_smallest_dx() * self.pf['mpc']
            if (halo['r_max'] / r_min < PROFILE_RADIUS_THRESHOLD):
                mylog.error("Skipping halo with r_max / r_min = %f." % (halo['r_max']/r_min))


r_max would be the distance to the furthest particle in the halo as found by HaloFinder.
But what is r_min ? And what is the basis for skipping this halo ?
