I've added updated zygo analysis. This is currently more up-to-date than my ELOG - something I will fix tommorrow! http://cvs.hep.ucl.ac.uk/viewcvs/esaBpmNote/?cvsroot=LC+Energy+Spectrometer for the tar ball and http://cvs.hep.ucl.ac.uk/viewcvs/esaBpmNote/built/?cvsroot=LC+Energy+Spectrometer for the pre-built versions. Thanks, Mark
