cds-question@unistra.frpulsarsradio-sourcesA large sample of pulsars has been observed to study their subpulse modulation at an observing wavelength (when achievable) of both 21 and 92 cm using the Westerbork Synthesis Radio Telescope. In this paper we present the 92-cm data and a comparison is made with the already published 21-cm results. The main goals are to determine what fraction of the pulsars have drifting subpulses, whether those pulsars share some physical properties and to find out if subpulse modulation properties are frequency dependent. We analysed 191 pulsars at 92-cm searching for subpulse modulation using fluctuation spectra. The sample of pulsars is as unbiased as possible towards any particular pulsar characteristics.2007A&A...469..607Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/469/607CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/445/243 : Pulsar subpulse modulation prop. at 21cm (Weltevrede+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/469/607https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/469/607http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/469/607https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/469/607https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/469/607http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/469/607GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/469/607/table2 (The subpulse modulation properties of the pulsars in the survey (at an observing wavelength of 92cm))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/469/607/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/469/607/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/469/607/table2?GETtext/xml+votable180.050000true3.573958347.77594440.0055555555555555566/426 1470 1676 1949 2787 3018 3157 3162 3367 3552 3616 3621 3731 4163 4227 4831 5955 6262 8068 8121 8277 9040 9240 9283 9719 11371 12259 12500 12526 12939 13053 13065 13152 13218 13287 13405 13719 13921 14078 14122 14273 14301 14306 14309 14313 14320-14321 14337 14344 14346 14415 14429 14549 14621 14649 14739 14842 14924 15009 15304 15365 15377 15496 15499 15646 15679 15751 16996 17247 17378 17532 18830 20166 20574 21016 21171 21455 21504 21957 22594 22765 22917 23727 23994 24040 24185-24186 24360 24541 25251 25763 27554 28135 28226 28843 28864 28872 28910 28921 28945-28946 29034 29059 29082 29108 29145-29146 29256 29285 29312 29334 29340 29369 29383 29387 29390 29422 29487 29521 29530 29550 29617 29625 29653 29680 29727 29789 29863 29883 29929 30102 30215 30252 30257 30269 30273 30286 30298 30300 30328 30332 30348 30356 30362 30417 30501 30594 30617 30619 30641 30657 30690-30691 30708 30713 30849 30871 30941 31031 31049 31078 31244 31344 31623 31809 31829 31933 32007 32048 32086 32116 32704 36540 39789 40366 40432 40667 40680 42870 42937 44308 44316 47975 47998 48080 48928 49129https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/469/607?format=asciiRadiodefaultJ/A+A/469/607/table2The subpulse modulation properties of the pulsars in the survey (at an observing wavelength of 92cm)P2?
