I analyzed the same analysis using SEIS_Z or ACC_Z and compared the results for both 2025-04-20 and 2024-11-09 data.
For both days, the results of using SEIS_Z and ACC_Z are consistent.

By the way, even before the shroud installation (2024-11-09), the linear-like coupling and its siderobe were found. 
On 2024-10-16 (before the stack connection), a ground shaker injection was performed (klog31337), but almost no significant excess was found in the DARM. (due to the shaking amplitude not being enough?)
