This involves a process of associating individual target detections to form a joint detection. These first detections have been followed by observations of a number of additional transitions. Claims of exoplanet detections have been made since the nineteenth century. The first neutrino detections were reported in Feb 2007. However these early detections were all gas giant sized, and many in eccentric orbits. A Poisson distribution is a necessary and sufficient condition that all detections are statistically independent. Advances in astronomical instrumentation have led to increasing numbers of new detections. In 2015, the number of thyroid cancers or detections of developing thyroid cancers numbered 137. Transition to track begins when the capture volume for two detections overlap. Teams earned points based on detections, diagnoses, and resolutions. To date there are no confirmed exomoon detections. Link 11 relies on a single platform to report positional information on sensor detections. The second disadvantage of this method is a high rate of false detections. The accuracy of these detections is determined by the concept of scent groups. That year the system got Chief of Naval Operations tasking to report whale detections.
