**total_pts = 46,517,276

* Coverage Region is CVM-H Low Resolution region
**dataset.geospatial_lat_min = 30.95
**dataset.geospatial_lat_max = 36.613
**dataset.geospatial_lat_units = "degrees_north"
**dataset.geospatial_lat_resolution = 0.01

**dataset.geospatial_vertical_min = -50.0
**dataset.geospatial_vertical_max = 4.0
**dataset.geospatial_vertical_units = "km"
**dataset.geospatial_vertical_resolution = 0.5
**dataset.geospatial_vertical_positive = "up"

*Variable Names, Units, and Ranges
**vp.long_name = "P Velocity"
**vp.display_name = "P Velocity (km/s)"
**vp.units = 'km.s-1'
**vp.valid_range = 0.0,10.0
**vp.missing_value = -99999.00
**vs.long_name = "S Velocity"
**vs.display_name = "S Velocity (km/s)"
**vs.units = 'km.s-1'
**vs.valid_range = 0.0,10.0

**rho.units = 'kg.m-3'
**rho.valid_range = 0.0,8000.0
**rho.missing_value = -99999.00

* CVM-H flags used in model extraction: 
**cvmh_param=USE_1D_BKG,True
**cvmh_param=USE_GTL,False
