CyberShake Study 15.10 takes the deterministic results from CyberShake Study 15.4 and adds broadband components.
Initial tests
We performed initial tests by using the Graves code from the current version of the BBP to synthesize stochastic seismograms, along with applying site amplification from CB2014. We used the Vs30 value taken from the same velocity model as the deterministic seismograms (CVM-S 4.26). We also applied site amplification from CB2014 to the deterministic seismograms. Then the deterministic seismograms were low-pass filtered at 1.0 Hz, and the stochastic seismograms were high-pass filtered at 1.0 Hz, and the results were combined. From this broadband seismogram we calculated PSA and RotD values.

Deterministic Site Amplification
We ran PAS and LADT with and without deterministic site amplification (using CB 2014). Here are the results:
