All the pulsars presented here were discovered in the HTRU mid-latitude survey, which has now been fully processed. The survey observed the Galactic plane in the region -120°-35° were regularly observed using the 76-m Lovell Telescope and those below this declination were observed as part of the HTRU timing programme at Parkes.

Not. R. Astron. Soc., 427, 1052-1065 (2012)>    =2012MNRAS.427.1052B    (SIMBAD/NED BibCode) ADC_Keywords: Surveys ; Pulsars Keywords: methods: data analysis - stars: neutron - pulsars: general Abstract:     We present 75 pulsars discovered in the mid-latitude portion of the     High Time Resolution Universe survey, 54 of which have full timing     solutions. All the pulsars have spin periods greater than 100ms, and     none of those with timing solutions is in binaries. Two display     particularly interesting behaviour; PSR J1054-5944 is found to be an     intermittent pulsar, and PSR J1809-0119 has glitched twice since its     discovery.     In the second half of the paper we discuss the development and     application of an artificial neural network in the data-processing     pipeline for the survey. We discuss the tests that were used to     generate scores and find that our neural network was able to reject     over 99per cent of the candidates produced in the data processing, and     able to blindly detect 85per cent of pulsars. We suggest that     improvements to the accuracy should be possible if further care is     taken when training an artificial neural network; for example,     ensuring that a representative sample of the pulsar population is used     during the training process, or the use of different artificial neural     networks for the detection of different types of pulsars. Description:     All the pulsars presented here were discovered in the HTRU     mid-latitude survey, which has now been fully processed. The survey     observed the Galactic plane in the region -120°<l<30° and     b≤15° (see Keith et al., 2010MNRAS.409..619K, for more details).     After the discovery and subsequent confirmation observations with the     Parkes 64-m radio telescope, pulsars with declinations     δ>-35° were regularly observed using the 76-m Lovell     Telescope and those below this declination were observed as part of     the HTRU timing programme at Parkes.
