Presentation by Jan on cross-check of the mass peak width for D+/- in data with the momentum resolution from HFT Embedding. The MC resolution gives a reasonable description of the mass peak width, significantly better than the old case using resolution from TPC Embedding.

Uses pion momentum resolution for kaons also, check if this gives better agreement at higher pT
Checks for 2016, suggestions to check for 2014 data as well!
