Table 1:

Figure of merit FoM per Eq. (2) for the three different survey set ups as described in the text: Full Incoherent, Core Coherent and Superstation Coherent.
Type $A/T_{\rm sys}$(m2/K) $N_{\rm beams}$ $\Omega$ (deg2) B (MHz) $1\vert N_{\rm stations}$ FoM
Full Incoherent 260 1 27 32 54 1.0
Core Coherent 170 128 0.006 32 1 0.8
Superstation Coherent 40 128 0.23 32 1 1.2

All parameters derived using the lowest observing frequency, 120 MHz. In the first column, $A/T_{\rm sys}$, we use 54, 36 and 12 stations respectively, of 24 tiles at 28 m2, and 140 K, while for the Superstation Coherent case we also multiply by 0.70 to correct for the lower sensitivity at the station beam edge.
