Well I don't know.  It would be an extraordinary achievement
for your 2970 signal to reach this far.  It needs a result
that can stand up to scrutiny.   I'd like to do some more
work with it to get an unequivocal detection at 5 sigma.

A few more days signal will help.   Adding 21st didn't
improve the peak, nor did the blanker settings I left
running last night.

For these runs I am blanking each antenna channel
independently, then mixing and phasing.  Usually I do
the mixing first and blank the composite signal.
While one channel is blanked and another isn't, the
mix is wrong.  That ought to be worse than blanking
after the mix.  With less than 5% blanking factor it
might not be much of an issue either way.

I can also look again at your previous 2970 tests,
stacking the same 14:00 to 19:00 window.
