keyword=Beam: hall A off: charge assymetry decreased by a factor of two

Hall A has been off since ~20min and the effect on our charge asymmetry width is striking (see plot below).

Note for the purists: the label on this figure is wrong, this is not the width of the charge asymmetry distribution but the precision of the mean charge asymmetry distribution measured each two minutes. That's proportionnal to the width of course..
