I am very happy that the field survey confirmed observations from ed
elastic analysis. :)
I think ed elastic channel can be used as a monitor on target spin angle
in future running, in addition to any Hall probes we might put into
target region. the sensitivity would not be as high as a survey like this
but it'd be almost real time.
