- ds2 : halo catalog-type dataset
- The dataset of the ancestor halos.
- radius_field : str
- Name of the field to be used to get the halo radius.
- factor : float, optional
- Multiplicative factor of the halo radius in which potential halos will be gathered. Default: 1.
- min_radius : YTQuantity or tuple of (value, unit)
