| + | * Pat: eigenfunctions measured above 0.2 Hz, not much signal below it. Gary agrees. | ||
| + | * Vuk: Correction of equation on slide 6. | ||
| + | * Daniel: for data points where there is a binary distribution (some retro and some pro), should we try to force the retro solution? This could change the mean and the median. | ||
| + | * Pat: not sure, had the same question. Will follow up via email. | ||
| + | * Victor/ | ||
| + | * Pat: velocity at low frequencies is maybe not modelled well with a linear or a power law. Maybe there are better choices? | ||
| + | * Victor: usually people don't fit velocity vs frequency with a parametrized curve, instead they use their data (or don't use some frequencies). | ||
| + | * Victor/Pat: could try to fix velocities from other estimates, and only estimate other parameters | ||
| + | * Vuk: it seems posteriors and priors are similar, not constraining the eigenfunctions more than we already did before the measurements. | ||
| + | * Victor: yes, the paper could simply state that the data is consistent with the model. | ||
| + | * Vuk: Maybe we can get away with some simpler statistical statement, showing that the model is consistent with the data? | ||
| + | * Victor: would be nice, but would not be the selling point of the paper. | ||
| + | * Vuk: let's then proceed with what we have. If we come up with a simple statistical test we can add it... | ||

| + | * Victor: this is the standard journal for geophysics research, so the emphasis should be on geophysics. It is OK to add on implications for physics. | ||
