Table 1 shows a breakdown of the CUBIC mass, based on measurements made at Wallops Flight Facility, and corrected for the removal of some of our shielding.
The materials were picked because of strength
to weight ratio, heat transfer capabilities and/or compatibility
with high vacuum systems. The major metals used are Aluminum
(6061-T6), Stainless Steel (304 CRES) and Copper (102).
The aluminum camera body is 
thick (min) and
has additional aluminum throughout for radiation shielding.
Stainless steel plates 
thick are bolted
to the side of the camera body in critical areas
to provide additional shielding.
The
total measured CUBIC mass is 31.07 kg.
A spreadsheet containing CG and MOI calculations is
shown in Table 2.
In the SAC-B coordinate system, the CG is
located at coordinates (X, Y, Z) = (+9.8 mm, +6.4 mm, +129.1 mm),
measured relative to the Top Dead Center of the
SAC-B structure (the bottom center of our bottom plate).
The moments of inertia are 
, 
,
,
measured relative to the CUBIC CG.
These estimated mass, CG, and MOI are our best estimates based
on measurements made at Wallops and corrected for the removal
of some of the shielding.
