TiRiFiC has originally been designed and implemented by Gyula I. G. Józsa, Franz Kenn, Thomas A. Oosterloo, and Ulrich Klein. Currently, TiRiFiC is mainly being maintained and developed by Gyula I. G. Józsa, with contributions and suggestions from many people. Apart from the original authors, we would like to mention:
The appropriate TiRiFiC reference in a publication is Józsa, G. I. G., Kenn, F., Klein, U., Oosterloo, T. A. 2007, A&A, 468, 731. While TiRiFiC has evolved quite a bit since then, the basic technique is described appropriately in this paper.
If you want to mention TiRiFiC in a talk, you may want to show the TiRiFiC logo and a link to this web page (http://gigjozsa.github.io/tirific/).
