Sometimes the time offsets are subtracted instead of added so that the time is off by e.g. 10 seconds or 1 minute. Sometimes someone makes a typo or mentions the wrong object id. In these cases the error is usually caught quickly, the original observer goes over his notes again and fixes the mistake. In science it's great if someone can verify your results. I really can't tell you if there is a parallel among "high res ground imagery of sats". Possibly not. However I can tell you that image processing techniques have made stunning progress (blind deconvolution for example) and will continue to make further progress. If someone 20 years from now wants to re-analyze a highly processed image on seesat-l and can't get to the original they are out of luck. In contrast, if someone wants to use 10 years of ppas data to determine satellite configuration based on flashes and sophisticated software, the data is all available. - George Roberts _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l -------------- next part -------------- An HTML attachment was scrubbed...
