We opened the X+ side hatch and the top belljar. We could not find any dirty items inside the chamber. Pictures are here.

We removed the geophone pods. The weight of each pod was 12.6kg. After closing the chamber, we measured the IP transfer functions. The resonant frequencies became 0.16Hz for L and T, and 0.4Hz for Y.
