One of my PCs which is usually rock solid has just got an AP invalid result for the first time in a very long time. http://setiathome.berkeley.edu/workunit.php?wuid=1659946592 I had a quick look at the three sets of data but could not see anything obvious. I did note that the two valids were both Macs running the same application version. Is there a reason for the invalid and anything I should be worried about? |

Nothing to be worried about. Not all signals are printed in stderr.txt. Probably a few signals (best pulses) are above treshold. This happsens. With each crime and every kindness we birth our future. |

One of my PCs which is usually rock solid has just got an AP invalid result for the first time in a very long time. As Mike said, nothing to worry about. The validator ignores single pulses which are less than 1% above threshold, and both the scale=6 and scale=7 ones in those results are at that critical level while the scale=9 one is well below it. For scale=6, the actual critical level is 130.14655071, and for scale=7 it is 214.75941787. Later versions of Lunatics builds will have more digits in the peak_power values shown in stderr, the 130.1 and 214.8 rounded values shown for those tasks leave it uncertain. There's a proposed change to the AP validator which would avoid that difficulty, but that kind of improvement is of course lower priority than other things which have been happening recently. Joe |

OK Josef and Mike, thanks for confirming that this is a seti problem and not my PC problem. Just a pity about the wasted processing time. |
