Problem with halo concentration and radius

[WeakDog]

I'm now trying to generate mock galaxies using my own halo sample. But I can not continue the working since the halotools requires the information of 'halo_nfw_conc' and 'halo_rvir', which I don't have in my halo catalogue. My question is: Can I still use the halotools to generate the mocks if there is no information of halo's concentration and radius in the halo calalogue?

For the halo radius, you will need to add this column yourself to your halo catalog before trying to populate the mock. You can do this with the halo_mass_to_halo_radius function:

from halotools.empirical_models import halo_mass_to_halo_radius

You can do the same thing for the concentration, using whatever c-M relation you prefer, or you can use the one calibrated in Dutton & Maccio 2014 by using the conc_mass_model keyword argument:

from halotools.empirical_models import PrebuiltHodModelFactory
model = PrebuiltHodModelFactory('zheng07', conc_mass_model='dutton_maccio14')

Thanks, it works
