Gravitational Wave Analysis Probably Separate from Detection

In confirming detection of gravitational waves, it was important to have interferometers separated in physical space. The coinciding detections imply confirmation. In the same sense, it will be asserted that analysis may necessarily have to be separated in space from detection and a method of analysis is proposed. Using this method, a possible confirmation of the separation may have been detected using 3 sets of already existing magnetic field data.
