    keyword=Request for inversion of Pair Synch

    It seems the the pair synch flip is seen by all DAQ. So I will request to do the flip at the source so that we are in the same condition as before. I checked with Hovanes in Hall B and he is fine with it. After talking with Riad, it seems that QRT was inverted on the board so they inverted but they did not do it for pair-synch and helicity. Since it that those inverted signals affect us, they are going to invert those too. So one should keep an eye on the logbook when they do it. We will restore all our settings to previous settings and everything should hopefully work and be same as before.

    I guess we will do the check with the charge asymmetry sign to make sure of the sign convention.
