Yokozawa-san performed a broadband acoustic injection for the OMC area, from 2024-11-11 02:04:00 UTC, with DAC output = 10,000 count.

I analyzed this data same as klog31293.

• reference data: 128s from 2024-11-11 02:01:00 UTC
• injection data: 128s from 2024-11-11 02:04:00 UTC

These results are attached:
