3.3.4.2 : MField

This table stored the dark matter density field put on a 256³ 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.

column	type	UCD	description
snapnum	int	time	The snapshot number for this field. This column corresponds to the snapnum column in the Snapshots table in MField.
phkey	int		The Peano-Hilbert key for this grid cell.
cic	float	phys.density	The counts-in-cell density in the grid cell, normalized by mean density. I.e. cic*10077696000/256³ gives the number of particles in each cell.
g1_25	float	phys.density	The density field smoothed with a Gaussian smoothing and radius 1.25 Mpc/h, normalized by mean density.
g2_5	float	phys.density	The density field smoothed with a Gaussian smoothing and radius 2.5 Mpc/h, normalized by mean density.
g5	float	phys.density	The density field smoothed with a Gaussian smoothing and radius 5 Mpc/h, normalized by mean density.
g10	float	phys.density	The density field smoothed with a Gaussian smoothing and radius 10 Mpc/h, normalized by mean density.
