UCVM cvmsi tapering for CyberShake Study 22.12

UCVM tapering

interp Zrange is set to [0,700] initially

related ucvm_query flags that affects tapering:

-L vs,vp,density (optional)

     example,  -L 200,-1,-1
         (only floor the vs to 200)

-m cvmsi,elygtl:taper

         (adding tapering interp to cvmsi)

-z zmin,zmax (optional)

         (zrange values, original 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

       default vs_floor 500, vp_floor 1700, density_floor 1700
       if there is a user-defined floor from ucvm_query command line option, use user-defined floors

       orig_ratio= vp/vs

       Rule 1,
          if vs < vs_floor:
             vs=vs_floor
             vp=vs_floor * orig_ratio

       Rule 2,
          if vp < vp_floor:
             vp=vp_floor
       Rule 3,
          if density < density_floor:
             density=density_floor

       Rule 4,
          if (vp/vs) < 1.45:
             vs=vp/1.45

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
