The various software packages (CORSIKA, sim_telarray) and models (QGSJet) print out the citation information in the log file. Now that simtools includes various hadronic interaction models, I thought that it might be nice if part of the output from each production run, simtools provides a file collecting the citation information of every package used in this production (including simtools itself). It can be also part of the log file instead, but just all collected in one place so it's easy to find.
This is far from important or urgent and is just a suggestion.
