  4. E Side bands(Data@600pb-1)

  5. E Sidebands Data31-44

  6. D+  Ks+ D+  K- ++ D+  K- ++ 0 D+  Ks+0 D+  Ks++ + D+  K- K++ Mbc distributions Data31-44(log scale)

  7. Rescaling (data)

  25. Number of Tags(599 pb-1) After a correction of 1.5±0.64 % based on the fact it is easier to find tags in +  events than in generic decays, the total # of tags is 347297±677±2223
