[PeterF, StefanB, Craig, Jenne]

We tried several different levels of RF9 modulation depth.  More than nominal is definitely bad, less than nominal (nominal during acquisition) doesn't seem to do a lot in DARM.  Colors should be consistent across plots, eg. ref 18 is brown is -6dB from nominal for all the attached plots.  Stefan has some more plots that he'll post showing correlations (or not) with various other channels.
