I think BOINCLogX just plots points in the sky from the work units your computer is processing. I don't think BOINCLogX does a whole lot more. The SETI@home algorithms are searching for repeating patterns in or around the 1420MHz frequency. I could be wrong but i think it might be + or - about 10 or 20 hertz.

99.99999 % of the stuff you see in the SETI screen-saver is interference. We live in hope that we will find that 0.000001 % that is not interference.

Lots more SETI science here; http://setiathome.berkeley.edu/sah_about.php

Helium has an emission line, why not use it?

Mind you unlike Hydrogen, you don't have H2 + H + H_inv emission lines in the RF band.

In any case, it is a thought.

The emission line of ionized Helium isotope (3 He III) is 8,665.650 MHz. While Arecibo can listen from 50 MHz to 10,000MHz, I understand that the feed used by SETI@Home extends only from 1200 MHz to 3000 MHz. I read that the Allen Telescope Array listens continuously from 500 to 11,200MHz, so it can be said to cover the Helium emission.
