- The beam tune: the quads were changed, then the beam was sent. It was at Y=1.5mm in 1H01,4A and 4B. The beam DID NOT move after the quad change! Perhaps 1.5 mm is not much at this energy.
- The energy lock on Hall C, pulsed, was used.
- The raster was ON.
- Run 13009 was taken with the Hall A laser OFF.

The measured polarization IS LOW for some unknown reason!!!
