The separation runs that analyse the northern galactic cap (Sloan Digital Sky Survey, or SDSS Stripes 9-27) have nearly finished - soon we'll be able to wrap all of that data together, and with data from Nathan Cole's PhD thesis, we'll have a nice scientific paper out in the next few months. We'll keep you notified. That doesn't mean that the separation code will be retired - far from it. We're starting new separation runs (the ones with "mix" in the name) that are testing the robustness of the separation code. We'll be running simulated data sets along side real data to test several aspects of the stream-fitting process. The main questions are: What would Milkyway@home do if something different from our model exists in the data? And how different would that something have to be in order to modify our results? Also, the release of SDSS Data Release 8 earlier this year gives us access to several stripes of data in the southern galactic cap. We are currently processing this data (It's not as continuous as the northern data, so we have to cut out areas with spotty data), and it will eventually run on Milkway@home. We are also looking to improve the code on Milkyway@home. My brand new paper studies the distribution function of stars in the Milky Way halo, and provides a new convolution kernel that should make Milkyway@home more effective. There are a few other results from that paper, and inside work, that we would like to implement in the Milkyway@home searches. When we update these functions, we will run stripes over again and look for differences. Long story short: We're almost done with one part of Milkyway@home's mission, but there's still plenty to do. Happy Crunching! Cheers - Matthew N |

Good news. What's the precentage of the finished work out of the total percentage? Any idea |

Thanks for the update, Matthew N Especially "Happy Crunching!" Any news about when completed results will be uploaded & more fresh work will become available to download? TIA, Ray |

I hope this a good place to put this. It is the first time I have been to the forums. Is the program running ok? I have only been on for about 6 weeks and everything was running good, but then nothing has changed since 11/22. I have 4 completed packets, and nothing to work on. The packes do not report, dispite me having his update several times a day for the last week. I thought maybe the system was down, because I could not get to the site either for several days. But now I get to the site and the uploads sill will not report. Any suggestions? |

It was down for days now. That is typical for MilkyWay. It will run good for a while then have problems. Doesn't expecting the unexpected make the unexpected the expected? If it makes sense, DON'T do it. |

Thanks, just wanted to make sure the problem was not on my end. |
