cds-question@unistra.frpulsarsradio-astronomyWe present the results of a systematic, unbiased search for subpulse modulation of 187 pulsars performed with the Westerbork Synthesis Radio Telescope (WSRT) in the Netherlands at an observing wavelength of 21cm. Using new observations and archival WSRT data we have increased the list of pulsars that show the drifting subpulse phenomenon by 42, indicating that at least one in three pulsars exhibits this phenomenon. The real fraction of pulsars that show the drifting phenomenon is likely to be larger than 55%. The majority of the analysed pulsars show subpulse modulation (170), of which the majority were not previously known to show subpulse modulation and 30 show clear systematic drifting. The large number of new drifters we have found allows us, for the first time, to do meaningful statistics on the drifting phenomenon.2006A&A...445..243Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/445/243CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/445/243https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/445/243http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/445/243https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/445/243https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/445/243http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/445/243GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/445/243/table2 (The subpulse modulation properties of the pulsars in the survey (at an observing wavelength of 21cm))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/445/243/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/445/243/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/445/243/table2?GETtext/xml+votable180.050000true3.573958347.77594440.0055555555555555566/426 1470 1676 1788 1949 2787 2874 3018 3157 3162 3367 3598 3614 3616 3621 3731 4163 4227 4831 5955 6262 8068 8277 9719 11287 11371 12526 12939 12975 13053 13152 13218 13287 13405 13719 13921 14078 14122 14273 14301 14306 14309 14320-14321 14330 14344 14346 14366 14415 14429 14431 14549 14649 14739 14842 14924 15009 15304 15365 15377 15496 15499 15679 15751 16996 17247 17378 17532 18947 20166 20574 21171 21455 21957 22058 23727 23830 23994 24040 24185-24186 24360 24541 25251 25763 27543 27554 28135 28226 28843 28849 28864 28872 28901 28905 28913 28919 28921 28945-28946 29059 29082 29088 29090 29108 29112 29162 29213 29256 29312 29334 29369 29383 29387 29461 29487 29504 29511 29516 29521 29524 29530 29532 29534 29550 29617 29625 29653 29789 29863 29929 30211 30215 30219 30223 30240 30246 30252 30256-30258 30269 30298 30300 30315 30328 30330 30407 30417 30594 30601 30603 30617 30630 30641 30657 30690-30691 30696 30700 30708 30713 30941 31228 31244 31344 31623 31809 31829 31933 32024 32048 32086 32116 35691 36540 39789 40366 40667 40680 42937 47975 48080 48928 49129https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/445/243?format=asciiRadiodefaultJ/A+A/445/243/table2The subpulse modulation properties of the pulsars in the survey (at an observing wavelength of 21cm)recnoRecord number assigned by the VizieR team.
