cds-question@unistra.frgalaxy-clustersgalaxy-classification-systemsWe study the supercluster shape properties of the recently compiled Sloan Digital Sky Survey (SDSS) cluster catalogue using an approach based on differential geometry. We detect superclusters by applying the percolation algorithm to observed cluster populations, extended out to z_max_<=0.23 in order to avoid selection biases. We utilize a set of shapefinders in order to study the morphological features of superclusters with >=8 cluster members and find that filamentary morphology is the dominant supercluster shape feature, in agreement with previous studies.2003MNRAS.344..602Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/344/602CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/123/1807 : SDSS galaxy clusters redshifts (Goto+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/344/602https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/344/602http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/344/602https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/344/602https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/344/602http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/344/602GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/344/602/table1 (List of the SDSS superclusters using R_pr_=26h^-1^Mpc.)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/344/602/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/344/602/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/344/602/table1?GETtext/xml+votable180.050000true154.00.20.0055555555555555566/0 17749 17751 17753 17770 17812 17829-17830 18004 18009-18011 18026 18074-18075 18092 18112 18777 23193 23210 25855 25941-25942 25957 25960 25962 26025 26196 26201 26276-26277 26282 26986 27046 27049 27052 27215 27225 27228 27237-27238 31386-31387 31395 31397 31399 31402https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/344/602?format=asciiOpticaldefaultJ/MNRAS/344/602/table1List of the SDSS superclusters using R_pr_=26h^-1^Mpc.K1Shapefinder K1 (2)src.morph.paramfloatK2Shapefinder K2 (2)src.morph.paramfloatRK1/K2 ratiosrc.morph.paramfloatrecnoRecord number assigned by the VizieR team.
