Message 1833592 - Posted: 2 Dec 2016, 4:31:10 UTC

I created a web interface for browsing current results. This lets you see the top-scoring pixels, and the top-scoring multiplets of various types. You can then drill down: click on a pixel to see its component multiplets, click on a multiplet to see its component signals, and click on a signal to see a "waterfall plot" of the signals in a time/frequency window. You can expand and contract this window.

The waterfall plots have an attach graph of the movement of the telescope across the sky during that time period (the movement of each of the 7 beams is shown separately).

As of now, the data shown here is based on the analysis of 200,000 pixels (out of 16M total). There are still issues and bugs in our algorithms, so nothing you see here is especially likely to be E.T.

How about a tad more info than pixel #abcdef and include something like RA and DEC with a link to sky plot?

I added RA and dec to the table.
I couldn't find a web source of skymaps for given RA and dec range; any pointers?

It used to have one in the Seti-Science link way back when Seti tried to show where Arecibo was pointing if it was collecting data.

That page is still in existence, but still 'vastly under construction' and not yet converted to the new format.

Google seem to have revised the 'visible' map API since that page was last reviewed or updated.

What is a multiplet? Can you explain the scoring a little more please?

A multiplet is the name given to a set of three or more signals where the peak shape is essentially "the same", and the centre frequencies are separated by the same frequency (n, n+x, n+2x, n+3x..... where n is the lowest centre frequency, and x is the offset to the next signal)

Hi David

Would it be possible to put up the date when you scored pixels and how many pixels were scored?

Thank you,
Bob

Thank you for your hard work!

How about make a coordinate conversion then place all pixels in aladin lite interactive sky atlas and create a overlay heatmap depending on variations of number of signals, scores and frequencies between adjacent pixels that would be great.

Hi David,

When I click on the RA/Dec Click for Sky map link for a particular Pixel. If I use this pixels ID.

https://setiathome.berkeley.edu/nebula/mc.php?s6=0&pixel=31057257&action=show_multiplets&sigtype=spike

The RA/dec looks correct on the web page (19.106413, 2.423914) but when I select the link for the skymap . I get the following error displayed:

Requested (ra, dec) is outside the SDSS footprint ( 286.6083, 2.32411 )

This happens to all pixels that I click on.. The RA is being passed with the incorrect value.

Regards,
BoincSpy ( Bob )
