| + | * Estimating wave speed along with the bi-exponential spectrum. Could re-run with an externally-determined wave speed, maybe from the transients. | ||
| + | * Would also like to use more transient events (currently using 20-30 of them). | ||

| + | * Gary can add something on the local geology. Perhaps better to include it in sections other than introduction. Make a link to why the mine developed it did, since this has an impact on the geometry of the array. So this may be a natural spot for this discussion (near the topography maps) | ||
| + | * For plots: maybe show some examples, and keep the rest for the electronic supplement. | ||
| + | * Victor: maybe would be nice to show something that shows the Rayleigh-wave properties. Maybe some of Pat's plots? | ||
| + | * Gary: maybe show seismograms to show a transient event, so how clearly you can identify the various components of it. Will try to find a good example(s). | ||
| + | * Should also add the topography plots from Daniel. | ||
