The SETI Signal protocol.

What happens if and when a Signal comes on the looong SETI mission?!
There’s a protocol that outlines the activities to be followed by any individual or organization that finds an extraterrestrial signal. In short, this document, constructed by an international group of SETI scientists, boils down to the following action plan in case of a suspected transmission from an alien world:
First, the discoverers should verify that the signal is really extraterrestrial and artificial, not man-made interference or natural, cosmic static. Having done so, those who made the discovery are to notify all the other signatories to the document so that they can independently proceed to check it. They should also inform national authorities. Next on the list of those notified are all the world’s astronomers, so that every available telescope can be used to study the source of the signal. And then there’s this, verbatim from the protocol; namely that the detection “should be disseminated promptly, openly, and widely through scientific channels and public media…”
Sounds straightforward, right?
