Note:
1) t1 and t2 are the starting and ending times for computing the averages, &lt;V_rms&gt;, Nu_top, Nu_botm, and &lt;T&gt; are averaged RMS 
   velocity, nussult number at the top and bottom boundaries, and temperature, respectively. T_mid_min, T_mid_max, velo_mid_min, and 
   velo_mid_max are the minimum and maximum temperatures, minimum and maximum velocities at the middle depth of the mantle.
2) The numbers in parentheses are standard deviations.
3) SHH06 is Stemmer et al. {2006}, RSZ96 is Ratcliff et al. {1996}, and YK04 is Yoshida and Kageyama {2004}. Resolution for these studies 
   is given in Table 1.
