(moderation:
but if it was, it would have been long before I joined E@H. With the mention of the first run of S3 analysis ending (I'm gathering this means there will be a second run, perhaps for redundency checking?), how many runs are planne? Does S4 data exist to be crunched next. Basically, what's in the cards as we move forward from here, in terms of what we will be crunching?

The redundency we talk of is run "internal" to the processing of specific work units. So, there would be no reason to re-test the "old" data already processed unless a major error was found in the Science Application that would invalidate the results ...
The scientists are likely to be running this process until the cows come home ...
Especially if a detection occurs ...
Yeah, I know multiple users

Yeah, I know multiple users run the same work units, and they get validated. I was inquiring as to the specific news item about

I took "begin a second round" to mean that we would be re-testing the same data (redundancy perhaps) a second time. Perhaps I read too much into the news item, but that's what it looked like they were saying, to me.
Still curious, as to what we'll be crunching as we move ahead, having completed the first round of S3 analysis...
Perhaps I should have asked this in the E@H science forum as well, it might have fit better in there, but too late... Thx though

I took "second round" to mean the same calculations on another round of data.
Now I see your interpretation I am not sure which is correct, perhaps one of the project scientists can enlighten us? Just what is this 'new round' within S3?

Actually, come to think of

Actually, come to think of it, either could be correct. It could be another round with the same data, or perhaps a subset of it, if they found a number of interesting results they'd like to confirm.
Or perhaps they might have broken the S3 data set into chunks, and processed each seperately. Normally, I wouldn't think of the latter as another round, but it isn't inconceivable they might have meant this.
Either way, I would be interested to know what we will be crunching/comming up the pipe. Also, if some interesting results were found, which is being further collaborated, that'd be nice to know as well. It'd give a sense of progress to the time/CPU cycles we're devouting here :D
I believe (but I am not quite

I believe (but I am not quite certain) that they meant a new set of data with the same calculations.
