Features of Kamiokande-II, IMB, and Baksan Observations and Their Interpretation in a Two-Component Model for the Signal

We consider the time, angular, and energy distributions of SN 1987A events and discuss the quality of their agreement with the expectations. A global interpretation is made by considering a simple model based on the standard scenario for the explosion. Despite the contrasting and confusing indications, a straightforward fit to the data provides a result that does not contradict but rather supports the expectations. The calculated electron antineutrino flux is applied to predict the relic neutrino signal.
