This simulation belongs to the simulations grouped as Box 64 – 186592 at the CLUES webpage.
It is a resimulation of the high resolution region (~ 2 Mpc/h radius) around the most massive dark matter halos (M31, Milky Way).
This resimulation contains no gas physics and star formation (“dark matter only”) and was performed using the Gadget-2 code.
The corresponding simulation with the same parameters, but including gas and stars, is called Clues3_LGGas. This contains also a table
AHFMatch, which links the halos of both simulations with each other.

Clues3_LGDM data in the database
The following table provides an overview on the database tables which are available for this simulation. For each table, a link to its “table type” is given. This leads to a page explaining the columns of the corresponding table in more detail.
Several tables may contain a Peano-Hilbert key (phkey) for each row, which can be constructed from the position using the hilbert key function. If not indicated otherwise, the hilbert order for this simulation is 7, i.e. there are 27 = 128 cells per dimension.
|Database table||Table type||Short description|
|AHF||AHF||AHF (Amiga Halo Finder) catalogue for all available snapshots. This table contains the main properties of the dark matter halos.
Please note that the AHF halo table contains the complete catalogue, including halos with a higher fraction of low resolution particles. Use e.g. fMhires > 0.9 to skip them.
