Can I just be the first to say that I've never posted to this forum before?

Looking forward to the ntpckr "Top Ten"!

...but does this not risk you giving away the coordinates for other researchers to then steal the SETI 'prize' and results thunder?

Very good for Science, but how good is that for your kudos and continued funding?

I would think that a web page is about as public as public disclosure could get. If anything, this will make it harder for others to steal the thunder. Berkeley SETI will have a few million witnesses that they saw it first.

And can I just say that I'm the first person to post twice to this Forum?

When can we expect the public version of the page to be available at http://setiathome.berkeley.edu/ntpckr.php ?

wow, it looks great!!

I think nobody's posting here because everybody is looking at the list.

May I ask for another addition? A link to the WU and/or the discoverers would be great!

That's a very good table that should spur some good interest.

Err... Can we also have a column to list how long a particular candidate has been in the top ten?

That should be useful to see what the 'churn' rate is, or whether the table quickly becomes static.

In the works:

* linking candidates to the people who processed them (something we hope to do soon, but it's a much harder problem than you'd think)

* the column "last updated" tells you how long the candidate/pixel has gone before another signal gets returned at the point in the sky (in which case the candidate gets rescored, and either goes up or down in the list). There's no "how long it's been in the top ten" yet - also a strangely difficult problem, and hopefully as we dig through all the data and catch up (months?) things will generally stay in the top ten really long, or drop out really quickly.

Nice account. Are you a bot? Misfit v6.0 wasn't supposed to be released yet. I think I've been downsized.

That's no good!

You've just got to be a v7xxx something to jump on the i7 Wintel bandwagon! (Even if you are still only a v6!!)

;-p

Cheers,
Martin


Addendum to explain the pun, see:

Wintel

The candidate list is interesting but would probably be easier to get to if the candidate # was a link to the ntpkr info.

You have to remember this project is always a version behind. Misfit v7.0 is currently being tested on BETA. But the more inactive a forum is the longer it takes to test. In the distant future Misfit v10 will be the workunits you crunch.

Matt,
A few questions;

Question 1. Would it be possible to show us a waterfall plot of what a real ET signal might look like if it appeared on a plot? And add the example to the FAQ.

Question 2. I Photo-shopped an example. In the waterfall plot for a real ET signal, would the spikes become more dense the closer the time line comes to zero, as seen in this doctored image? Maybe due to the earths rotation.



Question 3. In the waterfall plots, what is the pure black horizontal band across the image? Is it RFI that has been removed?

Example;



Question 4. I assume the Y axis on the waterfall plots is time. The scale is from minus one thousand two hundred to zero, then to plus one thousand two hundred. Is this seconds, as in one thousand two hundred seconds? Or should there be a decimal point, so the time line is from minus 12 seconds, to zero seconds, to plus 12 seconds?

Question 5. Could you add the scale to the graphs? So that it says the Y axis is Time in Seconds or T/Sec with the decimal point included. And the X axis with Frequency in GHz or Frq/GHz

Thanks Matt,
John.

does anyone know an easy way to convert the decimal values of RA and DEC into values that google earth will accept?

google earth (in sky mode) wants:
RA (HH:MM:SS.S), DEC (DD:MM:SS.S)

If you have a calculator with scientific functions, it is quite easy. There is somewhere a button named "deg". Deg = degree. DMS = Degree Minute Second. Enter the value to the calculator and press the button. It may be the reverse function of the button which you need. And for RA, the degrees should be the hours.

Christoph

EDIT

In Windoze calculator in scientific mode it is "dms".

It's not that easy, scrap this part. Should have tried it before posting.

actually using the windoze calculator you'll see it works just fine. degrees and minutes are all whole numbers the minute are put into decimals so as in the #1 point shows RA= 2.630859 angle which converts to a dms of 2.37510924 or 2:37:51.0924 DEC =26.714449 or 26:42:52.0164 note that the angle degree=hours the only diffence is the interpretation of the decimal number. I assume this is what you are looking at for a conversion. the conversion takes the 100ths into 60ths

Well that seemed like too much work to do each time I wanted to check a candidate....

Since "laziness is the father of invention", I wrote a quick php script to let me copy/paste from the Near-Time Persistency Checker page and get a result that I could copy/paste into Google Earth's "Sky" program in the "Location Search" field.

If anyone want to use it, feel free :)

SETI@home should've already done that. Instead of one individual graphic for each individual candidate IMO there should be a single graphic (perhaps even zoomable) showing all candidates. Each candidate being clickable to it's info page (or even a ballon popup with some minimal info). But perhaps the staff doesn't have time to write the code for it?
