We have identified points where CVM-S4 queries are stateful, specifically in the GTL region (~100m depth). By this, we mean that if we query the same point twice, CVM-S4 (and UCVM) returns different Vp, Vs, and rho properties for each query.
To investigate this, we will run some tests to determine if all CVM-S4 regions are stateful, or only the GTL regions. We will also look at how large the differences
Initial Observed Differences
Search Regions
Define two search regions, one in LA Basin where CVM-S4 has a GTL define. The second in the mojave where it is CVM-S4 background model. We will discretize at ~10.0m resolution. Basedon this link: Decimal Degrees, we'll descritze at 0.0001 resolution.
