Attachment #1 shows the DAC noise models for the General Standards 16-bit and 18-bit DACs we are expecting to have.
Attachment #2 shows the expected actuation range for DC optic alignment, assuming we use the entire DAC range for this purpose.
Attachment #3 shows the current and proposed (by me, just a rough first pass, not optimized in any way yet) de-whitening filter shapes. These shapes can be tweaked for sure.
Attachment #4 puts everything into displacement noise units. The electronics noise of the coil driver / de-whitening circuit have not been included so at high frequencies, the projection is better than what will actually be realizable, but still well below the BHD requirement of 3e-17 m/rtHz.
