As I understand, current tapes were processed by MultiBeam v6 and now get re-process with MultiBeam v7. Is it right?

And have been doing for several months. I get asked periodically why no new tapes have appeared in the SETI data distribution history. No new tapes (disks, actually) are known to have been received from Arecibo since 5 December 2014, and we'd processed all those before the turn of the year.

Then lets recall in what SETI MB v7 is different from v6?
Only Autocorrelation?

Yes.

If the project wanted to, they could use an analysis_cfg for these reruns which specified processing only the 128K FFT length with a single chirp limit of 30. That would give them the added Autocorrs with a minimum of redundant signal searches. All tasks would be extreme shorties (AR would make no difference). All dedicated crunchers would be screaming because they couldn't get enough work.

However, there's another reason to reprocess those tapes, the switch to PFB splitting is supposed to be providing cleaner data. I suspect that's more important to the science.

I am curious about this as well.
Are we not getting new data from Arecibo? If not, why not?
I am not sure what the usual turn around time for a box of drives from Arecibo has been in the past.

Or have we been getting more data but just not rolling it out due to unresolved database issues?

It was mentioned when the got the last shipment of data that is was only a partial full box of drives. Which they only did because we were out of data to split at the time.
It could be that whomever is paying for the time at Arecibo is doing something that is incompatible with the recording data for us. Such as looking for near Earth objects that may impact the planet.
There is a site that lists the scheduled activity for Arecibo. Which might give a hint as to how much they have been able to record.

There was talk about v8 of SETI

I think they are trying to get all the old data processed with the latest ap before they change anything.
