Pickling like this:
pickle.dump({'rvir':rvir, 'mvir':mvir, 'mgas': np.sum(h[1].gas['mass'].in_units('Msol')), 'mstar': np.sum(h[1].star['mass'].in_units('Msol')), 'mgashot': np.sum(h[1].gas[filt.HighPass('temp',1e5)]['mass'].in_units('Msol')), 'mgascool': np.sum(h[1].gas[filt.LowPass('temp',1e5)]['mass'].in_units('Msol')), 'Jtot':Jtot,'lambda':Jtot / np.sqrt(5.0/3.0mvir3 \ rvir) }, open(simname+'.data','w'))
