cds-question@unistra.frmagellanic-cloudsvariable-starsinfrared-photometryWe present results from an analysis of ~29000 RR Lyrae stars located in the Large Magellanic Cloud (LMC). For these objects, near-infrared time-series photometry from the VISTA survey of the Magellanic Clouds system (VMC) and optical data from the Optical Gravitational Lensing Experiment (OGLE) IV survey and the Gaia Data Release 2 catalogue of confirmed RR Lyrae stars were exploited. Using VMC and OGLE IV magnitudes we derived period-luminosity (PL), period-luminosity-metallicity (PLZ), period-Wesenheit (PW), and period-Wesenheit-metallicity (PWZ) relations in all available bands. More that 7000 RR Lyrae were discarded from the analysis because they appear to be overluminous with respect to the PL relations. The PL_K_s_ relation was used to derive individual distance to ~22000 RR Lyrae stars, and study the three-dimensional structure of the LMC. The distribution of the LMC RR Lyrae stars is ellipsoidal with the three axis S_1_=6.5kpc, S_2_=4.6kpc, and S_3_=3.7kpc, inclination i=22+/-4{deg} relative to the plane of the sky and position angle of the line of nodes {theta}=167+/-7{deg} (measured from north to east). The north-eastern part of the ellipsoid is closer to us and no particular associated substructures are detected and neither any metallicity gradient.2021MNRAS.504....1Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/504/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/345 : Gaia DR2 (Gaia Collaboration, 2018)II/351 : VISTA Magellanic Survey (VMC) catalog (Cioni+, 2011)J/AcA/66/131 : VI light curves of SMC and LMC RR Lyrae (Soszynski+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/504/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/504/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/504/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/504/1https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/504/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/504/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/504/1/table3 (List of LMC RRLs analysed in the paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/504/1/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/504/1/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/504/1/table3?GETtext/xml+votable180.050000true82.92220575-70.137826210.0055555555555555564/2065 2067-2069 5/8257-8259 8264-8265 8280-8281 8284 8448-8450 9352 9354 9376 9378 9384 9386 9728 6/32863 32885 33027 33069 33071 33128-33130 33132-33133 33140-33141 33804 33824 37386 37510 37516 37518 37540 37542 38920 389227.952274030004205e-20 1.7798557115773645e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/504/1?format=asciiInfrareddefaultJ/MNRAS/504/1/table3List of LMC RRLs analysed in the paperT0Epoch of maximum light (2)dtime.epochfloat[Fe/H]?
