Bayesian SED-matched detection method compared to the union of g, r, and i single-band detection. Left: the color-space locations of sources that are detected by both methods are shown as faint points, and sources that are detected by only one method or the other are highlighted. In this experiment, the detection thresholds were set very high and tuned so that both methods produced the same number of detections; this compares each method’s best detections. The Bayesian-only detections have typical colors of real objects, while the gri-union detections tend to be farther out in the extremes of the color space. Right: examples of sources detected by only the gri-union or Bayesian methods. The Bayesian-only sources have typical galaxy colors, while the gri-union-only sources tend to have very red or otherwise unusual colors.
