3. Replaced Ygreen REFL camera with ETMYT camera to see transmitted beam mode.
The camera that Yuta means in his elog from last night/this morning is the scattering camera at the Yend. The reason (I think) that he had to do this is that Manasa and Jan took the cable for the ETMYT camera, and were using it for their scattering camera. They mention in elog 8072 that they installed a camera, but they didn't say anything about having taken the ETMYT cable. This is the kind of thing that is useful to elog!
Anyhow, I have removed the Watec that belongs with the scattering setup, that Yuta borrowed, and put it back on the scattering table-on-a-pedestal. I then realigned the usual ETMYT camera (that Yuta moved out of the way to install the borrowed Watec), and put the ETMYT cable back to its usual place, connected to the Sony camera's box on the floor.
tl;dr: ETMYT camera is back to original state.
EDIT later: I put the Watec back, since it is more sensitive to IR, so now we have a Watec in the regular ETMYT place.
