I search a particular Subhalo at a particular snapshot; I make the tree of this Subhalo. I understand the linear tree, but I don't know how to interpret the 3D Tree:
-colors: indicates the velocity? which velocity? peculiar velocity, dispersion velocity or ...?
-dimension of the spheres: is it related to the solar mass of the subhalo, like for the linear tree?
-positions in the volume of the simulation : is it an overlapping of the position of every progenitor subhalo at every z?
Thanks for helping me,
This is mainly meant as a qualitative tool - for any analysis, I would make sure to look at the actual values of the tree data. To answer your questions:
yes, i need it just for a qualitative comparison. Thanks for your help
