  \caption[Key parameters for the five \textsc{Gimic} regions]{Key parameters for the five \textsc{Gimic} regions. The
    first four columns present the spatial location (in Millennium
    Simulation coordinates) and the nominal comoving radius of the regions at
    $z=1.5$. The following two columns give the mass of the gas
    particles in both the intermediate- and high-resolution
    simulations. The dark matter particle mass is a factor of
    $(\Omega_{\rm m}-\Omega_{\rm b}) / \Omega_{\rm b}$ greater. The next two
    columns show the number of particles of gas (or equivalently, CDM) particles within the zoomed region of the
    simulation, whilst the final column denotes the redshift at which
    each simulation was terminated. Note that the $+2\sigma$ region was not run at high-resolution.}
