With Hirata-san and Yasui-san.

Summary: we set the payload ready for the application the First Contact.

• We locked the suspended optical table.
• We locked the payload using the security structure screws in the IM, IRM, RM and mirror.
• Additionally, we fixed the RM onto the security structure beneath with two loops of PEEK cable ties.
• We adjusted the height and the lateral position of the protective jig, and brought it into contact with the HR surface of the mirror.
• We checked there were no significant gaps between the two using a brush and watching from the AR side.
