K pi pi MASS DISTRIBUTIONS:

          Fig 2:  the distribution of masses recoiling against the k+,
                  ie the k0 pi+ pi0 mass.  There is a peak near 1.3 GeV.

          Fig 3:   Fit the k0 pi+ pi0 mass distribution to a Breit Wigner
                   + F_{bkg} (= P_1[ Q^1/2 + P_2 Q^3/2 + P_3 Q^5/2; Q>0
                              = 0; Q<0   Q = M_kpipi - M_thresh)

          Fig 4:   the distribution of masses recoiling against the k0,
                   ie the k+ pi- pi0 mass. This also has a peak around 1.3.

pipi and kpi masses:   
          
          Fig 6:  The combined pi+/- pi0 mass distribution for the two
                  samples described above.  Lots of events is the
                  rho region, but no clear peak.

          Fig 7:  The combined k pi mass distribution for the two samples.
                  There is some k*(890).
