Basin Query Notes
Contents
Example Comparison Plots OpenSHA versus UCVM basin_query:
Log-ratio of basin_query to OpenSHA:
OpenSHA-produced Z1.0 and Z2.5 Plots are posted here
Scatter plot of basin_query vs OpenSHA:
Those plots do show a difference in the registration of the model in Mei's files. This is probably related to the issue Christine described.
A zip file with the code, all data files, and all plots is posted here as that may be more convenient than manually downloading everything:

How Plots were Produced
Kevin created all of the plots discussed (and a few more). I did this by creating a new OpenSHA class, ZFilePlot. That class is posted here:
A build of this tool, along with the bash script and all data I used to run it is posted here:
http://opensha.usc.edu/ftp/kmilner/cvm_data/2017_z_file_compare/
The usage of the tool (requiring java 8 and after downloading the jar file) is:
java -cp opensha-cybershake-all.jar scratch.kevin.cybershake.ZFilePlot <min-lat> <min-lon> <nx> <ny> <grid-spacing> <max-z> <data-file> <label> [<compare-file> <compare-label>]
The "max-z" argument scales the color pallet to this value (I use 10 for Z2.5 and 2 for Z1.0). All plots are in km (the files themselves are in meters, but I scale them before plotting). The last 2 arguments are optional, for creating ratio/scatter plots. For example, to compare basin_query Z2.5 to OpenSHA Z2.5:
java -cp opensha-cybershake-all.jar scratch.kevin.cybershake.ZFilePlot 33.35 -123 1551 1201 0.005 10 basin_query_mpi_cca_z2.5_n20_second.result BQ\ CCA\ Z2.5\ Second opensha_cca_second_z2.5.bin OpenSHA\ Z2.5\ CCA\ Second
The forward slashes in the label arguments are for spaces within a single argument. While I hope this tool will be useful to Mei in the short-term, I don't believe that it should be bundled with UCVM (it relies on an opensha web service that may change/move at any time), and I still believe that a python/matplotlib plotting script should be created within UCVM.
