cds-question@unistra.frpulsarssurveysWe reprocessed the Parkes Multibeam Pulsar Survey, searching for single pulses out to a DM of 5000pc/cm^3^ with widths of up to 1s. We recorded single pulses from 264 known pulsars and 14 Rotating Radio Transients. We produced pulse-energy distributions for each pulsar which we fit with log-normal distributions, power-law tails, and a power-law function divided by an exponential function, finding that some pulsars show a deviation from a log-normal distribution in the form of an excess of high-energy pulses. We found that a function consisting of a power-law divided by an exponential fit the distributions of most pulsars better than either log-normal or power-law functions. For pulsars that were detected in a periodicity search, we computed the ratio of their single-pulse signal-to-noise ratios to their signal-to-noise ratios from a Fourier transform and looked for correlations between this ratio and physical parameters of the pulsars. The only correlation found is the expected relationship between this ratio and the spin period. Fitting log-normal distributions to the energies of pulses from RRATs showed similar behaviour for most RRATs. Here, however, there seem to be two distinct distributions of pulses, with the lower-energy distribution being consistent with noise. Pulse-energy distributions for two of the RRATs processed were consistent with those found for normal pulsars, suggesting that pulsars and RRATs have a common emission mechanism, but other factors influence the specific emission properties of each source class.2018MNRAS.479.5413Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/479/5413CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/479/5413https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/479/5413http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/479/5413https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/479/5413https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/479/5413http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/479/5413GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/479/5413/table1 (Single-pulse detections of known pulsars from the reprocessing of the PMPS)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/479/5413/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/479/5413/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/479/5413/table1?GETtext/xml+votable180.050000true112.3845417-18.6117250.0055555555555555566/21504 28711 28730 28735 28807-28808 28812-28813 28816 28818 28825-28826 28843 28847 28849-28850 28854 28863-28864 28869 28872 28878 28896 28901 28919 28921 28927 29057 29059 29079 29082 29090 29094 29099 29103 29108 29130 29162 29168 29174 29176 29248 29265 29461 29495 29504 29509 29511 29516 29521-29522 29530 29532 29534 29550 29552 29556 29649 29653 30208 30210 30215 30221 30252 30256-30258 30265 30269 30280 30298 30311-30312 30315 30325 30328 30331 30333 30348-30349 30356-30357 30400 30404 30417 30420 30505 30592 30594 30598-30600 30610 30619 30621-30622 30631 30638 30641 30646 30657 30690-30691 30696 32007 37207 37244 37332 37339 37341 37351 37361 37374-37375 37701 37704 37714 37717 37745-37746 37828 37848 37864 37900 37905-37906 37910 37922 37929 37933 37946 37948 37958 37990 38018 38020 38040 38402 38568 39275 39280 39389 39977 41464 41468 41470 41535 41561 41583 41593 41607 41615 41625 41654 41656-41657 41665 41672 41674 41677-41679 41682 41685 41689 41695 41697 41701 41704 41706 41710 41715 41719 41736 41747 41757 41765 41771 41781-41782 41789 41799 41818-41820 41828-41829 41840 41871 42146-42147 42155 42172 42196 42208 42222-42223 42232-42233 42348 42356 42366-42367 42372 42382-42384 42391 42394 42397 42401 42422 42432-42433 42437 42450 42456-42457 42466 42471 42477 42481 42487 42503 42510 42515 42531 42821 42832 43012 43025 43044 43144https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/479/5413?format=asciiRadiodefaultJ/MNRAS/479/5413/table1Single-pulse detections of known pulsars from the reprocessing of the PMPSSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
