Hi Marty,

I'm sure the paper (preprint likely when?) will use these detections to help verify/calibrate the search sensitivity. The solid pickup of a 2.1 ms pulsar at that large a DM (almost 300) gives one hope. The ATNF pulsar cat lists the S1400 as 1.3 +- 0.4 mJy, which is pretty faint. It also shows it to be a binary, just long enough period (95 days) that PRESTO listed it as binary with a negative Pdot.
Thanks for starting this thread!
The truth is that right now it is a little bit too early in the game for us to start talking about publication plans. Although that wlll change fast if we find new systems and especially short-period binaries.
Our main focus now is to try and speed up the application. E@H is currently processing about 18 minutes of Arecibo data per day. We think that, via various tricks, improvements, optimizations, and GPU-enablings, we can increase this processing speed by almost an order of magnitude, to about 2 hours/day. This would enable us to catch up on the PALFA data set (which on average is about an hour of data per day). Hopefully we can get many of these improvements working this summer and fall.
Once we are making progress towards catching up with the full data set, we'll get back to publication plans, sensitivity calibration, etc. Fair enough?
Cheers,
Bruce
