Techniques previously used to analyze the spatial distribution and luminosity function of gamma-ray bursts (Hakkila et al. 1994, ApJ 422, 664) are applied to classical barium stars. One important ingredient necessary for this analysis is a map of sky sampling, which has been estimated from remarks made in the literature and is presented here. The analysis models interstellar reddening effects, and obtains results that are consistent with a disk population of intermediate age, coupled with a broad luminosity function. This work has been supported by NASA grant NAG8-192.
