This function calculates seismic parameters from an acceleration time series. Specifically, it calculates velocity vs time, displacement vs time, peak ground acceleration (PGA), peak ground velocity (PGV), peak ground displacement (PGD), Arias intensity vs time, total Arias intensity (Ia), time between when 5% and 75% of Ia has occurred (significant duration D5-75), time between when 5% and 95% of Ia has occurred (significant duration D5-95), mean period (Tm), pseudo-acceleration response spectrum (Sa), pseudo-velocity response spectrum (Sv), displacement response spectrum (Sd), and the Fourier amplitude spectrum (FAS).
