现在seti算的东西和以前算的东西，数据来源是一样的，只是分析方法有变化，主要是精度更高了吧，官方网站上有一段简介：

SETI@home Enhanced
Because Moore's law has been continually increasing the computing power of our volunteers, we developed a new SETI@home application with increased sensitivity. The original SETI@Home stepped coarsely through doppler drift rates. Because of this, there was a possibility of a Gaussian shaped or pulsed signal drifting out of a frequency bin during the duration of the analysis. These signals would be recovered later when the analysis is performed at lower frequency resolution. However, because more noise is included in the analysis performed at lower resolution, it decreases our sensitivity to such signals by a factor of two. Before now there wasn't enough computing power available to perform the full analysis at high resolution.
This new application has been released to the public. The BOINC core client automatically updated SETI@home to the new enhanced version once it was made available. Since there is more computing involved, users will notice a greatly increased turnaround time per work unit. Since BOINC credits by computation and not by workunit, this will not change the rate at which you receive credit. We also extended the return deadlines since clients will be crunching on workunits for longer periods of time.

你还是去编辑一下吧，要不等以后你上大学后会后悔的
