Abstract:

A drawing on the assembly of bottom filter in type-B payload is revised. There was mis-orientation, in the 3D CAD drawing, between the cap and the base plate of the bottom filter. The cap should be rotated by ~11 degrees to fix it. In the revised design, moving masses for the pitch control are not oriented properly to the beam axis of the interferometer. This may introduce a little complexity to the initial alignment of the bottom filter (the intermediate recoil mass).
