What data do you have to support you comparison claims regarding RJ - DJ
separation?
Also, the Dual Dirac DJ is NEVER the measured or actual DJ, and making
this statement suggests you may need to work at understanding DD extrapolation
method and QBER distribution. I like the Ransom Stephens paper on this
subject, as it is well written.
