The question about the radial velocity of the star from which the candidate SETI signal came, TYC 1220-91-1, seems a most relevant one. Without this
we have the very real possibility that a random bit of terrestrial interference, one of thousands, eventually happened to fall near
frequency' of 4462.3 MHz.
Given the radial velocity we could confirm that the true frequency, as sent, was essentially identical to the hydrogen times PI magic frequency. The
odds of that happening, due to random terrestrial interference, seems very low, and would appear to very much strengthen the true SETI signal
From what I read, determining the radial velocity of a star doesn't seem to be particularly difficult, given the necessary specialized knowledge and
access to professional grade equipment. It seems more a problem of taking the trouble to observe the light of this one, obscure star, out of a million
or so, at or above its level of brightness, via the spectroscope.
