3.3.1.2  :  MMField

This table stored the dark matter density field put on a 323 density grid. It stores both simple count in cells and also the values of the density field smoothed with a Gaussian kernel of various sizes.

columntypeUCDunitdescription
snapnum int time The snapshot number for this densityfield.
This column corresponds to the snapnum column in the Snapshots table in this database.
phkey int The Peano-Hilbert key for this grid cell.
cic float phys.density The cloud-in-cell density in the grid cell, normalized by mean density.
g1_25 float phys.density The density field smoothed with a Gaussian smoothing and radius 1.25 Mpc, normalized by mean density.
g2_5 float phys.density The density field smoothed with a Gaussian smoothing and radius 2.5 Mpc, normalized by mean density.
g5 float phys.density The density field smoothed with a Gaussian smoothing and radius 5 Mpc, normalized by mean density.
g10 float phys.density The density field smoothed with a Gaussian smoothing and radius 10 Mpc, normalized by mean density.
