The other authors were involved in the development and construction of experimental detectors, but did not contribute specifically to the analysis presented in the papers. Existing computer programs of the author were used in the research. One author had comments which could not be included because of a missed deadline. An author was involved in an earlier stage of a project, but did not contribute significantly to the results in the paper. Our papers are signed by all members of the collaboration.
Standard practice is to list as authors all students who collected data.
I considered this to be too much. I joined a pre-existing collaboration, whose third member contributed little to the project being done. One author was listed by the first author and I don't know why.
