When we disconnected the Pyload tomorrow, I lowered the keystone by about 5cm at F0 to seat all the filters so that the EY GAS filters wouldn't be lifted off due to the load from the Payload.

We lowered the keystone by about 5 cm at the top filter (named F0) to seat all the GAS filters so that the filters wouldn't be lifted off due to the load of the payload when we disconnected the cryopayload tomorrow.
- We opened the top chamber and the side hatch of cross tube. After that we fixed the BF by using the EQ stop.
- Last time(#7592), we didn't lower the keystone of the top filter sufficiently, which hit the LVDT for the vertical on the BF, so we evacuated the primary coil of the LVDT for the vertical on the BF to lower it sufficiently.
- In this evacuation of the LVDT, we didn't pull the cable out but placed it on top of the BF so it wouldn't fall on top of the BF.
- After the BF was seated, we lowered the keystone on the top filter by 5cm to seat the rest of the GAS filter; lowering the keystone by 5cm required a longer screw that was used for the pull screw instead of the original push screw, so we replaced it and lowered the keystone.
- At that point, the keystone hit the yoke, so we removed the magnet to make it go down.
- With it lowered about 5 cm, all the switches on all the stages of the release sensor lit up, so we decided that we could seat the all filters and finished the today work.
