Hi all, I found that using a Enzo dataset I was getting slightly different numbers when 1) using the list of dark matter particles selected by creation_time < 0.0 In [97]: sph_dm = sph['creation_time'] < 0.0 In [98]: print "%12.12e" % (sph['ParticleMassMsun'][sph_dm]).sum() 1.211311468567e+11 2) compared to summing the dark matter particles inside a 3D container with TotalQuantity In [101]: print "%12.12e" % (sph.quantities['TotalQuantity']('Dark_Matter_Density')[0]*vol/Msun) 1.188937185993e+11 I'm wondering if the field and particles are handled differently when being counted as inside or outside the 3D container? From G.S.
