[Marie, Jenne]

Marie suggested that we run A2L, which we did.  She was totally right - we should have done this a week ago!  We win about an order of magnitude in sensitivity at low frequencies.  This will make things much easier for the calibration team.

Attached is a spectrum showing the enormous improvement.  This reduced the coherence between DARM and CHARDY, but not to the low level that CHARDP is, so there is probably more that we could do to get even better sensitivity with A2L.

Edit:  The new A2L values have been saved in both the down.snap and observe.snap sdf files.
