Arguments

M	Moment magnitude, a numeric value
ip	The index of working period in the per-defined periods: (-1, 0, 0.01, 0.02, 0.03, 0.04, 0.05, 0.075, 0.1, 0.12, 0.15, 0.17, 0.2, 0.25, 0.3, 0.4, 0.5, 0.75, 1, 1.5, 2, 3, 4, 5, 7.5, 10)
R_RUP	Closest distance (km) to the ruptured plane
R_JB	Joyner-Boore distance (km); closest distance (km) to surface projection of rupture plane
Rx	Site coordinate (km) measured perpendicular to the fault strike from the fault line with down-dip direction to be positive
Ztor	Depth(km) to the top of ruptured plane. 999 if unknown
dip	Fault dip angle (in degree)
F_RV	Flag of reverse fault. 1 for reverse fault, 0 otherwise.
F_NM	Flag of normal fault. 1 for normal fault, 0 otherwise.
HW	Falg for hanging wall sites. 1 for sites on the hanging wall side of the fault, 0 otherwise.
Z10	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). Reference site condition is 1130 m/s.
Vs30_code	Code for Vs30 measurement. 0 for measured Vs30; 1 for inferred Vs30
region	Region indicator: 0 for global (incl. Taiwan); 1 for California; 2 for Japan; 3 for China; 4 for Italy; 5 for Turkey
d_DPP	Centered on the site and earthquake specific average. d_DPP = 0 for median calc (by default)

Value

An array of four values: (1) median spectral acceleration prediction (in g); (2) logarithmic standard deviation of spectral acceleration prediction; (3) logarithmic standard deviation of within event residuals; and (4) logarithmic standard deviation of between event residuals at the period of ip.
