I got scared and asked Eli to turn off MD9- and MD9+. At 6700A, what we used to call the superelastic region has become the elastic radiative tail region so there's a lot more signal in it now.
However it appears that it would be okay to turn MD9+ back on at any time. Just in case John needs it for something.
The other background detectors look okay, signal amplitude-wise. They aren't really measuring background now though.
