3.3.21.3 : Snapshots

This table links the expansion factor, redshift, Hubble constant, and lookback time to the integer index of the snapshot (0-67) from the miniMillennium-II Simulation. Almost all other tables in the various miniMillennium-II databases have a snapnum column that corresponds to the one in this table.

column	type	features	description
snapnum	integer	NOT NULL	The order of the snapshot, from 0 (z=127) to 67 (z=0)
a	real	NOT NULL	The expansion factor at this snapshot
z	real	NOT NULL	The redshift at this snapshot
Hz	real	NOT NULL	The Hubble constant at this snapshot, in km/s/Mpc
lookBackTime	real	NOT NULL	The lookback time at this snapshot, in 10⁹ years
