On the LIGO site I see that the S6 Run will start on July 7 with double sensitivity compared to S5. Shall we receive some of its data?

Yes we will! See this paper that describes an improved analysis algorithm that is intended to be used for S6 data crunching on Einstein@Home.

So, does this mean that we'll be wrapping up the current S5 run early, in order to start crunching S6 data?

Well, I wouldn't hold your breath ... :-)
If past runs are a guide then I'd expect some decent period before sufficiently good quality long detector intervals have been established.

Now that you've brought it up, I've looked at the detector log for Hanford. Found some amusing entries :

Oops, left CapsLock on. We lost 2 hours of science mode trying to figure out why awg would not come back. Finally started bootfest on Linux boxes in the control room. Came back nicely when done.

Tuesday maintenance, there are several other items to do but the following are the one done today:
-Dark Offsets
-Site inspection
-Checked Chiller
-Relieved SUS biases
-Cosmic Reboot
-Received Supernova alarm test

Activities by Contractors:
-Laundry delivery
-Oscar landscaping
-Port a potty service
-Paradise delivery
-Garbage pick up
-Other equipment deliveries to the site

So it seems The Universe was restarted last week, and Hanford is now the best place to be ( with adequate ablutions too ) ..... :-) :-)

Maybe I should resurrect the Detector Watch thread, seeing as they're taking data again. It looks like after a few stumbles last week the IFO is getting into the groove with a good duty cycle last night : H1 Science Data 20303 s ( 70.5 %).

Cheers, Mike.

( edit ) Livingston logs show much the same, but with more Trains, Planes and Automobiles ( + earthquakes + helicopter + wind + don't know ) being sensed.

Definitely not.

For the Arecibo Binary Pulsar Search, you can basically take detector-data as it is generated and feed it into the search pipeline, generating WU almost from live date.

It's different for the LIGO searches. Every workunits that you receive for S5R5 contains detector data spanning several months. It is the task of the science app to "combine" these months worth of data into a list of candidate signals. Therefore, the mere S6 WU creation can only begin after enough detector data has accumulated.

That aside, evaluating the S5R5 data fully has its own scientific merit and there's no reason to leave holes in the analysis.
