YES and NO

YES because some work units are full of craps, noises, local interferences, etc and the SETI program stop processing this bad work units. We all have one once in a while.

NO because we are having too many at the moment. I must have crunched 1 or 2 on classic in a year period but arround 20 since BOINCing. It could be due to the fact that since BOINC is pretty much in a test phase and since there is not enough work for everybody, SETI is being using those bad units to fill our caches. I don't know, I am just guessing.

If they're trying to fill our queues and keep us happy, it'd be to their advantage to let us re-crunch known good units and not pass out the noisy ones again.

Agree. But what could explain why we're having so many now. I've had 4/20 on my last download batch. More then I ever had in one year of classic. Could it be just coincidence ? Are we crunching data from new tapes ? I have noticed that a lot of those bad units were labeled 04my04.

Thanks Marc.

Mine is from 05my04. I've got 2 or 3 every 18 WU.

Units recorded on the 4 5 6 of May are currently being distributed for processing.
No indication that those units are bad but there is a lot for sure.

Well, one guess is that they might be trying to look through the Clarke belt and are seeing alot of noise from geostationary satellites.

... or a cub scout troup on a hike with a big stack of GMRS radios.

Thunderstorms might be another reason -- does anyone know what the weather was like on the 4th of May in Puerto Rico?

Could be all these reasons together plus a UFO passing by generating noises
with its SIMFPP (supraconducting inverse magnetic field positron propulser)...

Using WU2WAV, (http://gamma.nic.fi/~jknutar/wu2wav/) I once converted one of my work units that looked more than a bit noisy to a wave file, was most surprised to find a somewhat distorted voice broadcast of some sort, it sounded like perhaps TV or satellite, always a learning experience this seti thing.

I've also experienced that with WU2WAV and kept a record of it just in case.

noise in WU Was yours similar?

No it's not. Just trying to find out why.

Very similar, I do remember Vincent Price's voice in my work unit, but the audio was a bit more constant, just more distorted, didn't keep mine on file unfortunatly, so others can't hear, you've done great to keep yours for future reference, who'd believe it otherwise? Vincent Price in a work unit - Wow!

They aren't really "bad" WUs. The resulting output file will simply contain too much data (and much too large) for the @Home users to be expected to return. This doesn't mean they can't be processed, or are garbage and should be thrown out. ET may just be hiding in one of these noisy WUs.

I don't know if it still says this, but the stderr message used to say that the WU warrants further study by S@H... I take this to mean that the data is indeed intended to be processed at some point.

And I don't believe they send them out on purpose. Without doing the initial scan, (the first couple of minutes when you start processing a WU) unless they are aware of some telescope skewing, they don't know what the data tape contains.

I don't agree. I think they have transferred their complete MP3's folder of Metallica
on the wrong directory and they have sent the tapes to Berkeley. I am currently
crunching "Sad But True" and "Wherever I May Roam"

Only jokking of course and I agree with you.
