Hi,<br>
<br>
While running HaloProfiler, I am seeing this...<br>
<br>
P001 yt.lagos   ERROR      2009-12-08 15:53:22,403 Skipping halo with r_max / r_min = 1.885682.<br>
<br>
<br>
<br>
I looked at yt/extensions/HaloProfiler.py...<br>
<br>
           r_min = 2 * self.pf.h.get_smallest_dx() * <a href="http://self.pf" target="_blank">self.pf</a>[&#39;mpc&#39;]<br>
            if (halo[&#39;r_max&#39;] / r_min &lt; PROFILE_RADIUS_THRESHOLD):<br>
                mylog.error(&quot;Skipping halo with r_max / r_min = %f.&quot; % (halo[&#39;r_max&#39;]/r_min))<br>
<br>
<br>
r_max would be the distance to the furthest particle in the halo as found by HaloFinder.<br>
But what is r_min ? And what is the basis for skipping this halo ?<br>
<br>
