I have been crunching these since they first came out and I have a couple of questions.
As I understand it BRP5 beta became BRP6.
The data comes from the Parkes telescope in Australia.
Have we found any pulsars there?
IIRC the BRP4 data came from the Arecibo observatory and a fair number of pulsars were found. I find it strange that none have been found in the southern sky.

No, BRP5 and BRP6 are different. Whilst both use data from the Parkes telescope, BRP5 was known as the "Perseus Arm Survey" (PAS) and BRP6 uses data known as the "Parkes Multi-beam Pulsar Survey" (PMPS). This latter data set was first processed as BRP3. The current BRP6 run is referred to as PMPS-XT because it is doing a deeper, extended search through the PMPS data. If you look at the sticky threads in the very forum you posted in, you will find this thread, where Benjamin has taken the trouble to document all this. Sticky threads are there for a reason, after all :-).

Yes, all BRP4 runs are based on Arecibo data. If you take a look at the home page of this website, in the left hand navigation area you will see a sub-heading, "Science information and progress reports", under which there is a link, Parkes Multibeam Pulsar Survey - last updated 2016/04/18. You will find there have been lots of discoveries from the southern sky. With an extended search, more can be anticipated, which is why we are doing BRP6.

Cheers,
Gary.
