  An experiment consisting of a network of sensors can endow several advantages
over an experiment with a single sensor: improved sensitivity, error
corrections, spatial resolution, etc. However, there is often a question of how
to optimally set up the network to yield the best results. Here, we consider a
network of devices that measure a vector field along a given axis; namely for
magnetometers in the Global Network of Optical Magnetometers for Exotic physics
searches (GNOME). We quantify how well the network is arranged, explore
characteristics and examples of ideal networks, and characterize the optimal
configuration for GNOME. We find that by re-orienting the sensitive axes of
existing magnetometers, the sensitivity of the network can be improved by
around a factor of two.
