I was wondering whether the LHaloTree was constructed based on only dark matter particles or all particles. Thanks!
Dark matter only particles. SubLink also uses dark matter only particles.
You mentioned needing "Sublink_Gal", are you sure? This uses stars and gas, instead of DM particles, but in practice the results are almost always the same as "SubLink" itself.
Yes, I am sure. If you are interested, I can send you more details.
I have added functionality to the API so that you can download individual trees from SubLink_Gal, exactly as before for SubLink (for a given subhalo). You can download all four types: full, MPB, MDB, simple. Let me know if you run into any trouble.
