If only noise is entering the antennas, these four possibilities will be equally likely and each will happen one quarter of the time. If we multiply the bits together and average the result, the average will go to zero.
1. The bits are the same and are both +1,
2. they're the same and both -1,
3. West is -1 and East is +1,
4. or East is -1 and West is +1.
In the very unlikely event we receive a signal from ETI (Extra Terrestrial Intelligence),
we will spot a positive number or a negative number in our data. Sort of like the -20
that popped out of the data shown below, but THIS IS NOT FROM ETI!!!. Well, I really don't
know where it came from. My guess it is noise, but it could have been a glitch in the radio links.
I SAY IT IS NOT FROM ETI.
The spacing in time between lines in the tables is about 1.6 seconds. We use the Julian Date
because it keeps track of time and date with one number. The number changes by one every day.
