Using negative detections to estimate source finder reliability

Instrumentation and Methods for Astrophysics 2015-06-03 v1

Abstract

We describe a simple method to determine the reliability of source finders based on the detection of sources with both positive and negative total flux. Under the assumption that the noise is symmetric and that real sources have positive total flux, negative detections can be used to assign to each positive detection a probability of being real. We discuss this method in the context of upcoming, interferometric HI surveys.
