Why are we running 3 year old work units? Lets get some new ones in new areas of the sky. Come on SETI lets go! |

Why are we running 3 year old work units? Lets get some new ones in new areas of the sky. ACTUALLY we could be recrunching ALL of the old units in the future. New Science means that the old units may yet have valuable info in them. Right now there is a box of tapes from the Telescope that are in a box. Matt reaches into the box and pulls one out and splits the data on it into chunks for us to analyze. The tapes are in no particular order and there is no order in the way they are pulled out. The analogy for re-examing the old units goes something like this...we look at a mirror with just our eyes and see a smooth, shiny piece of metal. We look at that same mirror with a microscope and we see that it in fact is not as smooth as we at first thought, and is in fact very bumpy. We look at that same mirror with an electron microscope and we see that what we thought was a solid piece of metal is in fact a bunch of MOVING atoms! Different ways of looking at the same mirror produced different results, the hope is that the same can be said about the old units. YES new units ARE being produced, I am not sure that it is happening as we speak, but the telescope IS still producing data. The Allen Array should be on-line within a couple of years and produce even more units. There are other telescopes that will also be brought on-line to produce even more units, the Southern Hemisphere one for one. |

AFAIK Matt also takes deliberately tapes of different dates so that there is always a certain mix of WUs, so the chance of receiving dozens of noisy 2-min-WUs in one chunk is smaller. :-)= Greybeard All about BOINC: BOINC-Wiki (by Paul D. Buck) |

Ah...going thru the old data:)That vould bee nice,it would reminde me of the good old days when i began chrunching,becos i also have Seti map view(it also documents in vich year the data was taken:) Scorpions - Wind Of Change |

Basically Bryan, the Arecibo telescope can only "listen" to a limited portion of the sky. As such, it's already scanned all of the sky in it's range many times over. And since we don't know when a significant signal may be received, there's really no advantage to going chronologically. So newer WUs aren't going to give any advantage over older ones. :) And as has been pointed out, it's very possible that when the newer more sensitive science application leaves beta, we might even look at previously completed WUs again. |
