I don't remember seeing one that high, however, I haven't been doing this very long. It finished early too, usually it takes around 40 minutes. | |

That's the astropulse early exit which serves the same function as result_overflow in MB tasks. It doesn't happen as often because there are separate limits of 30 for the two basic types, where MB quits on a total of all types it processes. Joe | |

That's the astropulse early exit which serves the same function as result_overflow in MB tasks. It doesn't happen as often because there are separate limits of 30 for the two basic types, where MB quits on a total of all types it processes. It appears to have found an active area. Here's another one that threw down the slide-rule and raised it's hand in half the time as the last; Found 30 single pulses and 30 repeating pulses, exiting. percent blanked: 0.00 This one almost reached the point; single pulses: 22 repetitive pulses: 30 percent blanked: 0.00 It would be nice to know if we are analyzing reruns of Gilligan's Island or if something more interesting is making all that noise. If I had the coordinates I could look it up on the program Starry Night and see if there are any Pulsars close by... | |

If I had the coordinates I could look it up ... The coordinates are in the WU files (both for astropulse and MB):

P.S. Notepad do not show the layout OK, use WordPad (lines end with only LF (0A) (Unix style)) ____________ - ALF - "Find out what you don't do well ..... then don't do it!" :) | |

If I had the coordinates I could look it up ... You only get Azimuth & Zenith readings for the AP? The Azimuth is 'upside down' similar to an optical scope? It would be much easier with a RA & Dec as with the MB. I'm not sure how to decipher the az & zen readings given. If you could work that out to simple AZ & ALT from Arecibo I could use that... Where do you obtain a copy of the File? Say, this one; ap_12no12aa_B3_P0_00126_20121217_25009.wu | |

Where do you obtain a copy of the File? Say, this one; ap_12no12aa_B3_P0_00126_20121217_25009.wu If you're quick, you can download it from http://boinc2.ssl.berkeley.edu/sah/download_fanout/194/ap_12no12aa_B3_P0_00126_20121217_25009.wu (files are deleted from disk soon after validation) For how to work out the download url, see my thread WOW! Where on earth did that come from? | |

Where do you obtain a copy of the File? Say, this one; ap_12no12aa_B3_P0_00126_20121217_25009.wu Thanks. The RA & Dec is a little lower in the data. I got; <start> <time>2456243.7641723</time> <ra>6.1291691646237</ra> <dec>18.6518676557</dec> </start> <end> <time>2456243.7643278</time> <ra>6.1291429443197</ra> <dec>18.651741365036</dec> From Arecibo, that would be around 0120 Nov 12th, pointed around AZ 86 degrees & ALT 77 degrees, in Orion. According to Starry Night, there were 2 Pulsars within 4 degrees of that location at that time. PSR0614+2229 & PSR0633+1746 How wide is the Arecibo FOV? | |

I'm still getting these noisy, short AstroPulses. I'm having a hard time getting any at all, but the last two I managed to receive have been; | |
