The multibeam tessellation unit shown with circles depicting the half-power points of beams. (1992) and Johnston et al.!forum/barycorrpy. The periodicity search itself was based on that of the Parkes Southern Pulsar Survey (Manchester et al. The spin parameters of the newly discovered systems are similar to those of pulsars previously known in the search region. Moreover, by conducting a survey at high frequencies one is sensitive to pulsars with flatter spectra that were missed in earlier surveys. Among the most interesting new objects are two recycled pulsars with massive white dwarf companions (Edwards & Bailes 2001b), four with probable low-mass He dwarf companions, two isolated MSPs, and one ‘slow’ pulsar with a very narrow pulse profile and small period derivative, suggestive of recycling in a scenario similar to those of the known double neutron star systems (Edwards & Bailes 2001a). Principally, a 3D position-fix could be derived from observations from three different pulsars located in different parts of the sky, but in reality more would be required.

In the case of results from this survey, the plethora of interference signals across the spectrum resulted in the misinterpretation of many pulsars as interference. Two pulsars show very regular drifting subpulses and are analysed in detail elsewhere (Ord et al., in preparation). 8 shows the distribution of S/Ns in the best detections of new and previously known pulsars.
