We introduce a new method to estimate the probability that an extragalactic transient source is associated with a candidate host galaxy. This approach relies solely on simple observables: sky coordinates and their uncertainties, galaxy fluxes and angular sizes. The formalism invokes Bayes’ rule to calculate the posterior probability P (Oi|x) from the galaxy prior P (O), observables x, and an assumed model for the true distribution of transients in/around their host galaxies. Using simulated… Expand
