  The SN1987A detection through neutrinos was an event of great importance in
neutrino physics, being the first detection of neutrinos created outside our
solar system, and then inaugurating the era of experimental neutrino astronomy.
The data have been largely studied in many different analysis, and has
presented several challenges in different aspects, since both supernova
explosion dynamics and neutrino flavour conversion in such extreme environment
still have many unknowns. In addition, the low statistics also invoke the need
of unbinned statistical methods to compare any model proposal with data. In
this paper we focus on a discussion about the most used statistical analysis
interpretation, presenting a pedagogical way to understand and visualize this
comparison.
