Violin damping - ETMX mode 6 (beating with ETMX mode1)
ETMX mode 6 was rung up when Oli gave me a phone call. After trying few settings unsuccessfully, I noticed that ETMX mode 1 was beating with mode 6 (they sit closely).
I have turned off the damping for ETMX mode 1 and then started damping ETMX mode 6 with nominal setting and this seems to be working fine.
Ryan Short also confirmed that the DCPD is now looking great (was increasing earlier due to the rung up modes).
Ryan Short has now put us back into Observing.
