  For a solid lattice, we rederive the Continuous Spontaneous Localization
(CSL) noise total energy gain of a test mass starting from a Lindblad
formulation, and from a similar starting point rederive the geometry factor
governing center of mass energy gain. We then suggest that the geometry factor
can be used as a way to distinguish between low temperature cantilever motion
saturation arising from CSL noise, and saturation arising from thermal leakage.
