Query: A few brief notes on the equivalence of two expressions for statistical
  significance in point source detections   The problem of point source detection in Poisson-limited count maps has been
addressed by two recent papers [M. Lampton, ApJ 436, 784 (1994); D. E.
Alexandreas, et al., Nucl. Instr. Meth. Phys. Res. A 328, 570 (1993)]. Both
papers consider the problem of determining whether there are significantly more
counts in a source region than would be expected given the number of counts
observed in a background region. The arguments in the two papers are quite
different (one takes a Bayesian point of view and the other does not), and the
suggested formulas for computing p-values appear to be different as well. It is
shown here that the expressions provided by the authors of these two articles
are in fact equivalent.
