  • replaced some 8 TeV ATLAS conf notes with the published results
    (ATLAS-CONF-2013-007 -> ATLAS-SUSY-2013-09, ATLAS-CONF-2013-061 -> ATLAS-SUSY-2013-18, ATLAS-CONF-2013-089 -> ATLAS-SUSY-2013-20)
  • corrected off-shell regions of some existing EM-type results (in three 13 TeV and eigth 8 TeV analyses).
