Query: A Bayesian on-off analysis of cosmic ray data   We deal with the analysis of on-off measurements designed for the
confirmation of a weak source of events whose presence is hypothesized, based
on former observations. The problem of a small number of source events that are
masked by an imprecisely known background is addressed from a Bayesian point of
view. We examine three closely related variables, the posterior distributions
of which carry relevant information about various aspects of the investigated
phenomena. This information is utilized for predictions of further
observations, given actual data. Backed by details of detection, we propose how
to quantify disparities between different measurements. The usefulness of the
Bayesian inference is demonstrated on examples taken from cosmic ray physics.
