Who decides what part of the sky to scan for data collection?

Is Arecibo the only source of the data?

Semi-random. We listen when others allow and we don't get to point. Also obvious restriction of where the telescope can point.

For now, but that is going to change assuming there is enough cash donated to get the software written to process data from additional sources.

That's kind of what I thought. Is this because SETI doesn't have the money to buy time on it? I wonder how much it costs? (Not that I'm planning my own mini-project, lol)

Cost is the biggest driver in piggybacking off other telescope users collection.
It is actually quite efficient to use the same collection time window for several projects that are not too interested in a specific point in space, but are doing a general sweep.
SETI@Home did get some money to do a little bit of targeted collection using the GBT(?), but that data has not been released to us as the splitters haven't been configured to work with it.

Green Bank? That's good. I was curious what other telescopes might be able to be used.

Currently two additional potential sources GBT & LOFAR. The main focus of the work appears to be on getting the data collection chain working on the GBT - that is from tapping and recording the signal through to the database work needed to store the results from our efforts, and hopefully something to screen those results. As far as I'm aware the GBT produces more data per second of observation than Arecibo, probably due to it having a larger bandwidth.

We don't need a bigger haystack. We need a bigger magnet.

...the wider bandwidth is a effectively a bigger magnet
