J. Hakkila et al., SELECTION EFFECTS AND TESTS OF REPETITION (CLUSTERING) IN THE BATSE 1B CATALOG, Astrophysics and space science, 231(1-2), 1995, pp. 23-26
A ''repeater statistic'' (derived from the two-point angular correlati
on function and accounting for location errors) is used to identify co
nstraints on the rate of burst repetition from the BATSE 1B catalog. B
ecause of the anisotropic sky exposure, repeating sources should creat
e additional effects in the large-scale distribution of close burst pa
irs.
