[yt-users] halo density profiling

Hello All, I'm trying to use the halo profiler, without much success. If I want to plot the density, do I need to use the weight_field? It says weight_field=None in the manual, but weight_field='CellMassMsun' in the cookbook. Is it the same for Dark_Matter_Density? Also, where can I see a list of things the halo profiler can in principle do? I coudn't find it on the site. Thanks a lot for your help, Irina
