[yt-users] how to find virial radius from enzo output

[Reju Sam John]

Dear All,
How to find virial radius from enzo output. From the following page
http://yt-project.org/docs/2.6/reference/api/generated/yt.analysis_modules.halo_finding.halo_objects.FOFHalo.virial_radius.html?highlight=virial%20radius#yt.analysis_modules.halo_finding.halo_objects.FOFHalo.virial_radius

I came to know that there is a function called virial_radius(). But how to
use it?
In the provided example

>>> vr = halos[0].virial_radius()

what is ' halos[0] ' ?


Thank You
