Abstract
We update the analysis of D meson mixing including the latest experimental results as of January 2014. We derive constraints on the parameters M 12, Γ12 and Φ12 that describe D meson mixing using all available data, allowing for CP violation. We also provide posterior distributions for observable parameters appearing in D physics.
