Tyler: 
- replacing David Fischer, 
- unfolding for differential ttbar Xsection
- also working on ttbarH 
- Using SVD unfolding (see discussion later), aim also for 2D unfolding!

Stefan: 
- Upgrade of TUnfold in new Root 6 version (bug fixes)
- unclear who used TUnfold for publications beyond H1. 

Pedro:
- Using TUnfold via RooUnfold for fwd-central dijets in CMS
- mainly DeltaPhi distribution --> main concern migrations into / out of sample - not between bins IN the sample. 

Stefan on SVD
- "cannot do in more than 1D" ?  ---> some discussion; maybe can work in 2D if you find scheme to split the regularisation when switching from one row of a histo to the next … 

Thomas
- pointing to Blobel's chapter on unfolding in new "Data analysis book …" to appear soon by Wiley. 

Stefan
- Thinking about improving unfolding by including systematic errors into the unfolding itself. 
--> longish discussion on syst errors and model dependence . 

Future? 
- Maybe find people to report on SVD method / overview presentations on methods? 
- Do's and don't's????
