For random locations, the HF accelerations are visually close. Also, when computing the RMS (Root-Mean squared) error, we get less than 0.01% of very small discrepancy. For example:
...
And the values of the RMS for that location per component are:
| Component | RMS |
|---|---|
| 000 | 0.0063201 |
| 090 | 0.0108189 |
| ver | 0.0016.065 |
A better validation is to compute the IMs from the text and binary BB accelerations and then compute the ratio. This ratio should be really close to 1. I have uploaded the text files that contain the results for several IMs to this page: pgv_ratio.txt, pga_ratio.txt, AI_ratio.txt, pSA0p5_ratio.txt, pSA1p0_ratio.txt and pSA10p0_ratio.txt for example.
