Caption

By combining the data from different telescopes, ClaRAN's 'confidence' level in its detections and classifications is increased. Shown as the number above the detection box, a confidence of 1.00 indicates ClaRAN is extremely confident that the source detected is a radio galaxy jet system and that is has classified it correctly. To the left is a radio galaxy jet system detected by ClaRAN using only data from radio telescopes. ClaRAN isn't sure what it's seeing here, giving two predictions, one covering the entire system with a low confidence of 0.53, and one covering the top jet only with a confidence of 0.67. To the right is the same galaxy, but with infrared telescope data overlaid. With the inclusion of data from infrared telescopes ClaRAN's confidence in the detection has increased to the highest value of 1.0, and ClaRAN now includes the entire system in its only prediction.
