:  DSubHalo

The DSubhalo table specifies the parent DHalo for each subhalo. It may be used to determine which subhalos belong to each DHalo. The SubhaloID column corresponds to the subHaloID column in the MFiels..FOFSubhalo table, and to the subhaloId column in the MPAHalotrees..MHalo table. So additional information about a subhalo may be obtained by joining to these tables.

DHaloID long meta.id The ID of the DHalo in the DHaloTrees..DHalo table to which this subhalo belongs
SubhaloID long meta.id The unique ID of a subhalo in the MField..FOFSubhalo table.
