Rjb	Joyner-Boore distance (km); closest distance (km) to surface projection of rupture plane
U	The indicator of fault type: 1 for unspecified fault, 0 for otherwise
SS	The indicator of fault type: 1 for strike-slip fault, 0 for otherwise
NS	The indicator of fault type: 1 for normal fault, 0 for otherwise
RS	The indicator of fault type: 1 for reverse fault, 0 for otherwise
region	Region indicator: 0 for global (incl. Taiwan); 1 for California; 2 for Japan; 3 for China or Turkey; 4 for Italy
z1	Basin depth (km): depth from the groundsurface to the 1km/s shear-wave horizon. 999 if unknown.
Vs30	Shear wave velocity averaged over top 30 m (in m/s)
return.type	The indicator specifies which type of data return: 1 for the med (in g)/sigma/phi/tau; 2 for F_E/F_P/F_S; 3 for r/Ln_Flin/Ln_Fnlin/f2/F_dz1/PGAr
coeffs	The coefficient table of BSSA 2014. You can use the internal saved data object, bssa_2014_coeffs
CA_F_AA	The updated anelastic attenuation value by the Buckreis et al 2023 CA subregional anelastic attenuation model. If unknown, input NA and the default BSSA14 is used.

Value
