2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/44957We review in brief the development and implementation of the Star integral, a tool yielding measurements of correlations much superior to conventional methods. A version for use in pion interferometry is explained. We also show how effects of non-poissonian overall multiplicity distributions may be eliminated if desired and quote results eliminating statistical biases arising in correlation measurements within small samples.12 pages, LaTex, 2 figures in tar-compressed uuencoded .eps format, Regensburg preprint TPR--93--25High Energy Physics - Phenomenologytext
