Recoil Studies
  Some plots that show the recoil calculated in different ways. 
  Recoil for nloose=0 and > 0. 

  First two of plots are for X_x calculated adding all jets (except the
  4 tight jets). Unclustered energy and jets below 8 GeV are corrected
  with the formula obtained from the W mass CDF note. The others at L5.

  Page 3: recoil does not include jets below 8 GeV.

  Page 4 includes in the recoil only the unclustered energy.
  
  Page 5-8: same as p. 1-4 for the case of nloose-jets>0

  Page 9 show the eta of the extra and nloose jets.
  Page 10 identical to 9. root problem I did not find out how to fix.
