1st
I noticed that the 1st beam is always the most outstanding beam.

Is that the 1 for total power of the signal.?

2nd

I saw it turn light grey, has that any extra value.?

I saw it too but I believe that is the radar noise SETI@home is fighting against, trying to filter it out (Radar blanking).

Could be, but seems a bit

Could be, but seems a bit easy, don't car much (nada) about seti doh

In one of the science threads this was explained. The "Power Spectrum" shows the frequency of any potential pulsar signal, from a Hz or so to about 200 Hz. Now, a low frequency "hit" can often be some form of interference like radar. Other quality metrics from candidates like these are looked at, and if it still looks good they'll run a refined search check on the data (e.g., the "PRESTO" plots on the (re-)discoveries page).

New hot candidates will be scheduled for confirmation observations at Arecibo or other available radiotelescopes. ABP hasn't yet found any new ones (I don't know if there are any significant candidates). The data we're crunching is about 4 years old on average; they processed this data earlier for non-binary pulsars and did confirmations of those during the campaign.

Yup. And you will be rewarded for your key pioneering role by being snap frozen in carbonite. Probably mount you in the Guggenheim. :-) :-)

Cheers, Mike.

Well, SETI is a good exercise

Well, SETI is a good exercise in pattern recognition. You try to filter some significant signal from noise. Once I had to read the book by K.S.Fu "Statistical pattern recognition" and it is an interesting subject.
