    "abstract": "We describe a statistical hypothesis test for the presence of a signal based\non the likelihood ratio statistic. We derive the test for a case of interest\nand also show that for that case the test works very well, even far out in the\ntails of the distribution. We also study extensions of the test to cases where\nthere are multiple channels.",
