This page has links to data files which contain the necessary information to reconstruct the mixing contours found in the publication of the FOCUS hadronic charm mixing results. The data files are two columns of numbers representing x'², y' space points. Thus, to plot x', you will need to take the square root of the first number.

• Data files for CP conserving fit (Fit C')
  • with statistical errors only
  • with statistical plus systematic errors

• Data files for CP violating fit to D0 and D0bar together (Fit D')
  • with statistical errors only
  • with statistical plus systematic errors

• Data files for CP violating fit to D0 and D0bar separately (Fit E')
  • with statistical errors only
  • with statistical plus systematic errors

One possible way to plot the x'-y' contour is with PAW. To plot the first file, kpi_xycontour_fitc_stat.dat, save this file to disk and then start PAW. Execute the following commands:

PAW > vec/read x2,y kpi_xycontour_fitc_stat.dat
PAW > sigma x = sqrt(x2)
PAW > vec/plot y%x ! CL
