Abell-like selection criteria. We investigate the effects of varying several parameters in our selection algorithm, including the magnitude range and radius from the cluster centre used to estimate the cluster richnesses. We quantify the accuracy of the photometric distance estimates by comparing them with measured redshifts, and we investigate the stability and completeness of the resulting catalogues. We find that the angular correlation functions for different cluster catalogues are in good agreement with one another, and are also consistent with the observed amplitude of the spatial correlation function of rich clusters.</eudc:description></eudc:descriptions><eudc:keywords><eudc:keyword>galaxy-clusters</eudc:keyword><eudc:keyword>galactic-and-extragalactic-astronomy</eudc:keyword></eudc:keywords><eudc:identifiers><eudc:identifier identifierType="URL">https://dc.g-vo.org/rr/q/lp/custom/CDS.VizieR/J/MNRAS/289/263</eudc:identifier><eudc:identifier identifierType="DOI">http://doi.org/10.26093/cds/vizier.72890263</eudc:identifier></eudc:identifiers><eudc:relatedIdentifiers><eudc:relatedIdentifier relatedIdentifierType="URL">https://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/289/263</eudc:relatedIdentifier><eudc:relatedIdentifier relatedIdentifierType="bibcode">1997MNRAS.289..263D</eudc:relatedIdentifier><eudc:relatedIdentifier relatedIdentifierType="URL">https://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/289/263</eudc:relatedIdentifier><eudc:description>Cone search capability for table J/MNRAS/289/263/catalog (The APM cluster catalogue)</eudc:description></eudc:relatedIdentifiers><eudc:creators><eudc:creator><eudc:creatorName>Dalton G.B.</eudc:creatorName></eudc:creator><eudc:creator><eudc:creatorName>Maddox S.J.</eudc:creatorName></eudc:creator><eudc:creator><eudc:creatorName>Sutherland W.J.</eudc:creatorName></eudc:creator><eudc:creator><eudc:creatorName>Efstahiou G.</eudc:creatorName></eudc:creator></eudc:creators><eudc:publishers><eudc:publisher>CDS</eudc:publisher></eudc:publishers><eudc:instruments/><eudc:publicationYear>1998</eudc:publicationYear><eudc:rightsList><eudc:rights>https://cds.unistra.fr/vizier-org/licences_vizier.html</eudc:rights></eudc:rightsList><eudc:fundingReferences/><eudc:contacts><eudc:contact>CDS support team &lt;cds-question@unistra.fr&gt;</eudc:contact></eudc:contacts><eudc:resourceTypes><eudc:resourceType>Dataset</eudc:resourceType><eudc:resourceType>AstroObjects</eudc:resourceType></eudc:resourceTypes><eudc:disciplines><eudc:discipline>astronomy</eudc:discipline></eudc:disciplines></eudc:resource></oai:metadata></oai:record></oai:GetRecord></oai:OAI-PMH>
