where

-118.23050 = longitude

  34.11750 = latitude

     45.00 = x in Cartesian coordinate (km)

    -15.00 = y in Cartesian coordinate (km)

      6.00 = depth (km)

    6.6277 = P velocity (km/s)

    1.7611 = Vp/Vs

    0.4067 = resolution diagonal element for Vp

    0.4596 = resolution diagonal element for Vp/Vs
