UCVM cvmsi tapering for CyberShake Study 22.12

UCVM tapering

related ucvm_query flags that affects tapering:

-L vs,vp,density (optional)

     example,  -L 500,-1,-1
         (only flooring the vs values)

-m cvmsi,elygtl:taper

         (adding tapering interp to cvmsi)

-z zmin,zmax (optional)

         (zrange values, default: zmin = 0, zmax = 350)

UCVM's implementation of ucvm-tapering is ..

     zmax fixed at 700

     outside of zrange

       below zmin,    process GTL (vs30 to vs)
       above zmax,    straight CRUST pass thru

     inside of range

       calculate target-taper values

       *** THIS IS NEW ***
                 Added an additional backend query
                 to get the original interp_crust value
                 and brought it back from backend to use for this
                 --- only implemented for plugin modules
                 *** What does this mean?
                 unless the non-plugin module set these values,
                 tapering is not going to work.  ie. cvmh
                 can not be tapered, (not sure if it makes sense)
                 but cvmhlabn could be tapered.


       if interp_crust.vs < target-taper.vs
           use interp_crust
       else
           use target-taper

       individually,
           if there is a user-defined floor, use that floor
           or else use predefined floor
              if value 'less'(exclusive) than floor
                   replace value with the floor
           if user-defined floor is NULL ie(explicitly set it to -1)
              skip the check

1. define UCVM_DEFAULT_VS_FLOOR 500.0
2. define UCVM_DEFAULT_VP_FLOOR 1700.0
3. define UCVM_DEFAULT_DENSITY_FLOOR 1700.0

the .firstOrSecond files are the ones that is needed for CyberShake study

Plot the binary file

To plot these files with ucvm_plotting, data ingest mode of plot_z10_map.py and plot_z25_map.py from ucvm_plotting is used but first needs to change those file name to have .binary file name so plotting scripts know how to parse the data

plot_z10_map.py -a s -s 0.0050 -b 33.25,-119.38 -u 35.08,-116.49 -c cvmsi,elygtl:taper -x 578 -y 366 -f cvmsi_taper_z1.0.binary -o cvmsi_taper_z1.0.png
