odd cap solutions #14

Open celsoa opened 8 years ago

Depth test for uturuncu event 20120202125816847 shows strange solutions at depths 5, 13, 14. Inversions are with a halfspace. Tests with other inversion ranges still produce same results. May need to check P arrival times from synthetics for these depths.

It would be nice to see the big beachballs (with polarity) for the anomalous depths.

Celso, do all solutions plotted fit all first-motion polarities?

The underlying issue seems to be that the synthetic P waveform is NOT aligning with the data for these odd cases. Why that is occurring is unclear.
