1. Low/High frequency - Network size trade off
Salvatore Vitale’s personal view subject to updates
MIT

2. Color code
Blue: concerning black holes Magenta: concerning neutron stars Green: concerning CWs Yellow: concerning stochastic. Orange: bursts Dashed: the unexpected
Some boxes are red and blue meaning that any combination of NS and/or BH is relevant.

3. Caveats
This plot should be taken as an indication of what science topics rely on which frequency and the number of detectors
It is not meant to be rigorous (at least in this version)
It’s something I put together to show clearly how the answer to “what’s the optimal network configuration” strongly depends on the scientific question one is trying to answer
I will try to keep this to date and improve it with suggestions I receive
You are welcome to use this diagram, just please kindly credit it
