# Script to set up a renormalized cluster.
#
# The assumption is that this will be drawn from a uniform volume of 600 Mpc,
# and the high res. region will be XXX 16/h Mpc in size.
# Planck cosmology will be used.
# Waves: Big cube used 768**3 waves
# Renormalized: Ultimate resolution is 768(gas)/1152(dm)^3 in 25Mpc cube.
# Mpc cube, or 1536/2304 in 50Mpc cube. Of the 1536, the top 24**3 waves will
# overlap the 768**3. From 24 to 768 (Nyquist) will be filled by the high res.
# Group 201824 from cosmo600
#
# Med res run: down to 384**3 in 25Mpc
