Instrumental California Earthquake Catalog

This is in good shape for both northern and southern California because STEP currently utilizes it?

However, there might be some magnitude-completeness issues if we use low-magnitude seismicity to infer foreshock/aftershock statistics and/or stress changes?

There also may be issues related to automatic access to the data, such as: 1) is there a standard interface for both N. and S. California? 2) Is there versioning in terms of magnitude estimate updates?

It is not yet clear exactly how, or if, the WGCEP will use this data. Use would most likely be with respect to Earthquake Probability Model 3 of UCERF 3.
