Attached are two side by side 10 hour trends during observation mode w/ Quite_90 blends on Z in the left group and 45mHz Z blends in the right group.  These are about four days apart, 8 vs 12 Dec.  I've scaled each plot to be the same on the two trends.

The first four signals are X & Y Ground motion and the seismic environment is a mix with some better others worse in the second group.  The ASC signals are very close with only suttle differences.  We need to look at spectra now but this says the ASC doesn't care or this yardstick is too coarse.
