-You should try to reach out to anyone else who may also want to use these ntuples, and see if they'd like to add or change anything. This is usually done through your working group (either by email, or for new productions, by presenting at a WG meeting). For this, you can start by getting in touch with your WG conveners (see [here](http://lhcb.web.cern.ch/lhcb_page/collaboration/organization/lhcb-conv/Physics_history_and_Sub-structure.html) to find out who they are).

 In addition, the Analysis Productions coordinator(s) may also have some feedback on your additions/changes.

 One of the requirements for the successful review is that your analysis code is preserved.  
 Scientific integrity means having transparency on each step of the research as well as reproducibility of the results.
