S5R4 的一些消息

Youth

1. 应该是时间不准，多算几个就差不多准了

2. 没有，自从离开学校，就没怎么用过代理了：）

没优化算S5R3的包还是比算R4包划算。

今天再看已经是共需314天了。。。

项目服务器状态页面已经更新，S5R4的运行时间目前预计为164天，估计实际跑个100天差不多了，也可能只是指S5R4a吧。

Thanks! I guess a question would be is this new analysis considered more sensitive in digging the signals out of the data, or perhaps it is just another way of approaching the problem, or perhaps it is analyzing data that has not been analyzed previously?

The latter. The S5 LSC Science run lasted about two and a half years, when we started S5R2/3 only the data of the first year was available. S5R4 is looking at the rest of the data from S5, where the sensitivity of the detectors was higher than in the first year. Also we got more usable data out of the second year, which improves the sensitivity of the analysis. That, however, also means that for the workunits the data volume has increased and the amount of computational work necessary to process them, too.

S5R4和S5R3的主要区别：

LSC的S5阶段大概持续了两年半，之前本项目的R2/R3都只是分析第一年的数据，而R4是分析后来的数据，这时的探测器已经比前一年更为灵敏。第二年的运行过程也得到了更多有用的数据，这可以提高分析过程的灵敏度，因此，R4任务单元的数据容量有所增加，相应的，处理数据所需的时间也会有相应的增加。
