A long time ago in the newsgroup sci.astro.seti which is far, far away I asked after the release of the accumulated results of all the work units.

I didn't think much of the answer but it was sort of the researchers get to use it for whatever they want even if unrelated (I can buy that) and they get first use of it (I am less happy with that one) and that maybe some day if they get around to it CDs of the results might be for sale. I found the last not acceptable. [Yes, CDs. I asked that long ago.]

I assume there is more than one of us who would like to play around with the results just to see what they are like.

Assembling the results does not appear like much of a problem -- famous last words but if someone is analyzing the results for something more than HI THERE they are already somewhat organized.

And as we now have bittorent there is no need to create and sell (hopefully) DVDs. There simply needs be a modest breakdown by gigabyte groups of data and the torrents made available.

If the results are being analyzed then they are organized so just release that. If the explanation of the organization is too hard, release the analysis source code and we can reverse engineer it.

As it is bittorrent there is no necessary demand upon the any single computer including those at Berkeley. It has been going on enough years that if it takes six months to get a collection of data it hardly matters. We are patient animals.

So when do we get our own copies of the results? Real soon?

Here are the results; http://setiathome.berkeley.edu/sci_status.html

They are still working on them Matt. SETI@home and BOINC are open-source projects so, if you know what your doing, everything you want if freely avalable.

SETI@home results so far;
---------
Number of signals checked = GaZillion's and GaZillion's
Aliens found = 0

Video's avalable = millions of them on Youtube.

That is not what I mean. I am talking about each and every returned result associated with a time and RA and DEC.

The essence is that there should be complete disclosure of what is done with results that indicate that a further look needs to be done. My understanding is that SETI @home piggybacks on the other research on the Arecibo radio Telescope. As such, SETI has little, if any chance, to revisit the sector of sky that a promising result might indicate is worth another look.

I wonder if a signal counting out the prime numbers 20db above the noise would: first of all make the list of promising results, and whether or not it would be recognized by humans, and whether or not that sky sector would be re-examimed by Arecibo.

My impression is that many (thousands ?, millions ?) of anomalous results are being stockpiled--don't know if any are actually examined again at the current time. I hope I am wrong about this but somehow this is my impression.

I am confident that all signal processing and other techniques looking for intelligence in the presence of noise are well known by and are being done at Berkely Boinc SETI. So the results may be successfully archived but there are undoubtedly some results that are a few needles in the vast haystack--will they come to light--hope so-- but don't know.

I don't know. In the last 4 years that i have been following this project i have not seen anything that would indicate that the guys in the lab are checking anything. I do continuously hear about server crashes, software upgrades, computer problems, basically everything except real science about trying to detect real signals. In 4 years, i can honestly say that i have not heard one scientist on this project post a message or chat about SETI@home science results.

So why do i stay with this project???
I keep following this project because even if it never succeeds, its still worth looking. In theory, some day, they might just accidentally trip over a repeating signal in the data. Also, its very promising that the NSF and NASA gave this project grant money in the last year. If the Kepler telescope finds an earth like planet, the public excitement will be massive and this, in turn, will pave the way for bigger money grants for SETI projects like this one. This project could be massively successful if it had more money to eliminate the computing problems and work on real SETI science instead of computing. Its all about money really, SETI@home have never had enough to allow them to concentrate on the real science.

Work on NTPCKR is ongoing, there have been changes to the code most every week. That's what will correlate what signals have been seen where, and how often. Persistence is the fundamental criteria for signals which may be from a source at astronomical distance.

And there have been hints that once NTPCKR is operational, participants will have a chance to help in determining which persistent signals are the best candidates for further observations, and which are obvious reoccurrances of RFI.

Gentlemen,

I am not suggesting looking for something the S@H project overlooked. There is processed background level noise data in the processed results. The returned results say there is nothing I in that noise. But there is noise in that noise and there are tens of millions of noise samples over years in the returned results. I have no idea what is there or if there is anything of interest. But a lot of people have contributed. The folks at Berkeley have long since had a first cut at using it. So when is our turn?

You most likely will not improve the signal processing but will maybe catalog recurring signals of interest and then see if they persist, and are not coincident with known earthbound or satellite signals.

Say for example I am merely interested in the directional dependency of background noise. Now can I ask when the processed results will be available?

Matt,
I think its unlikely you going to get the type of results you are looking for.

But if they are ever going to publish anything, this is where i think you should look for it; http://seti.berkeley.edu/. Currently they don't have what you want.

Speak of the Devil, the SETI@home scientists just published a science paper, its the front page news item. (They must have been reading your message Matt_Giwer).

Get the new paper here; New Paper on the NTPCkr and RFI Rejection

So there is non ET information to be found in the results.

Again I ask when we, the people who crunched the data, get access to the crunched data results.

It was maybe five years ago I asked this question on sci.astro.seti. I was told there was some consideration of doing it but there was a problem of how to release it given the best distribution at the time was on DVDs. Burning and distributing would be something completely different for the Berkeley staff to do.

Since then there is bittorrent which distribution doable.

By example today's RedHat linux releases are mainly by bittorrent. That is a company in business to make a profit yet all kinds of seeders participate including universities. Even I have participating in the seeding albeit simply as a short test case.

I do not see a reason the results are not sorted by some simple criteria and grouped into 4483MB files and released as a torrent.
