Unfolding Meeting 4.5.2011
connected: Tim Adye, Natalie Milke, Pedro Cipriano, Gero Flucke (Nikolai Gagunashvili had technical problems)

Just a breif round of activities:

• Tim reported
  • finished the PHYSTAT proceedings about RooUnfold
  • got user requests to deal with correlated mesaurements
  • thinking to about dealing with uncertainties in the transfer matrix
  • interfacing most recent (beta) versions of TUnfold (S. Schmidt - now with pseudo-inverse of the covariance) and TUnfoldSVD (K. Tackmann) that are newer than what is provided by recent (stable) ROOT
• Natalie worked on bias tests
• Gero did not do anything besides proof reading of PHYSTAT proceedings and discussing with Pedro
• Pedro is working on getting further used to TUnfold, studies like the proposed blind tests shoulkd be presentable at the next meeting.

It is a pity that thr eis not much progress, but that is what we need to live with - the algorithm comparison is a useful study. Gero will setup  a doodle again for beginning of June.
