cds-question@unistra.frglobular-star-clustersvisible-astronomysloan-photometryMultiple Stellar Populations (MSPs) are a ubiquitous phenomenon in Galactic Globular Clusters (GCs). By probing different spectral ranges affected by different absorption lines using the multi-band photometric survey S-PLUS, we study four GCs - NGC104, NGC288, NGC3201 and NGC7089 - that span a wide range of metallicities. With the combination of broad and narrow-band photometry in 12 different filters from 3485A (u) to 9114A (z), we identified MSPs along the rectified red-giant branch in colour-magnitude diagrams (CMDs) and separated them using a K-means clustering algorithm. Additionally, we take advantage of the large Field of View of the S-PLUS detector to investigate radial trends in our sample. We report on six colour combinations that can be used to successfully identify two stellar populations in all studied clusters and show that they can be characterised as Na-rich and Na-poor. For both NGC 288 and NGC 7089, their radial profiles show a clear concentration of 2P population. This directly supports the formation theories that propose an enrichment of the intra-cluster medium and subsequent star formation in the more dense central regions. However, in the case of NGC 3201, the trend is reversed. The 1P is more centrally concentrated, in direct contradiction with previous literature studies. NGC 104 shows a well-mixed population. We also constructed radial profiles up to 1 half-light radius of the clusters with HST data to highlight that radial differences are lost in the inner regions of the GCs and that wide-field studies are essential when studying this.2022MNRAS.515.4191Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/515/4191CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/515/4191https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/515/4191http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/515/4191https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/515/4191https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/515/4191http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/515/4191GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/515/4191/ngc104 (NGC 104 photometric catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/515/4191/ngc104?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/515/4191/ngc104?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/515/4191/ngc104?GETtext/xml+votable180.050000true4.923757778-72.778760.005555555555555556Cone search capability for table J/MNRAS/515/4191/ngc288 (NGC 288 photometric catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/515/4191/ngc288?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/515/4191/ngc288?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/515/4191/ngc288?GETtext/xml+votable180.050000true12.96509-27.618690.005555555555555556Cone search capability for table J/MNRAS/515/4191/ngc3201 (NGC 3201 photometric catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/515/4191/ngc3201?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/515/4191/ngc3201?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/515/4191/ngc3201?GETtext/xml+votable180.050000true153.9092-46.633610.005555555555555556Cone search capability for table J/MNRAS/515/4191/ngc7089 (NGC 7089 photometric catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/515/4191/ngc7089?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/515/4191/ngc7089?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/515/4191/ngc7089?GETtext/xml+votable180.050000true323.0821-1.3992050.0055555555555555565/4772 8330 6/16644-16645 16647 16656-16658 19094 19096-19097 33315 33318 33324 33326 33409 35759 35770 38123 38126-38127 38465 38467-38470https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/515/4191?format=asciiOpticaldefaultJ/MNRAS/515/4191/ngc104NGC 104 photometric cataloge_J0378magError in J0378 magnitudemagstat.error;phot.magfloate_J0395magError in J0395 magnitudemagstat.error;phot.magfloatJ0410magJ0410 magnitudemagphot.mag;em.optfloate_J0410magError in J0410 magnitudemagstat.error;phot.magfloatJ0430magJ0430 magnitudemagphot.mag;em.optfloate_J0430magError in J0430 magnitudemagstat.error;phot.magfloatgmagg magnitudemagphot.mag;em.opt.Bfloate_gmagError in g magnitudemagstat.error;phot.magfloatJ0515magJ0515 magnitudemagphot.mag;em.optfloate_J0515magError in J0515 magnitudemagstat.error;phot.magfloatrmagr magnitudemagphot.mag;em.opt.Rfloate_rmagError in r magnitudemagstat.error;phot.magfloatJ0660magJ0660 magnitudemagphot.mag;em.optfloate_J0660magError in J0660 magnitudemagstat.error;phot.magfloatimagi magnitudemagphot.mag;em.opt.Ifloate_imagError in i magnitudemagstat.error;phot.magfloatJ0861magJ0861 magnitudemagphot.mag;em.optfloate_J0861magError in J0861 magnitudemagstat.error;phot.magfloatzmagz magnitudemagphot.mag;em.opt.Ifloate_zmagError in z magnitudemagstat.error;phot.magfloatrecnoRecord number assigned by the VizieR team.
