By combining data from the OGLE-IV catalogue with mid-infrared photometry from the Spitzer Space Telescope, we have determined the 3.6 and 4.5{mu}m LLs for the Magellanic Clouds using ~5000 fundamental-mode classical Cepheids. Mean magnitudes were determined using a Monte Carlo Markov Chain (MCMC) template fitting procedure, with template light curves constructed from a subsample of these Cepheids with fully phased, well-sampled light curves. The dependence of the Large Magellanic Cloud LL coefficients on various period cuts was tested, in addition to the linearity of the relationship. The zero-point of the LL was calibrated using the parallaxes of Milky Way Cepheids from the Hubble Space Telescope and Gaia Data Release 2. Our final calibrated relations are M_[3.6]_=-3.246(+/-0.008)(log(P)-1.0)-5.784(+/-0.030) and M_[4.5]_=-3.162(+/-0.008)(log(P)-1.0)-5.751(+/-0.030).2021MNRAS.500..817Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/500/817CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/500/817https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/500/817http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/500/817https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/500/817https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/500/817http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/500/817GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/500/817/table7 (Final mid-IR catalogue for 2352 LMC and 2672 SMC fundamental mode Classical Cepheids in the Magellanic Clouds)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/500/817/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/500/817/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/500/817/table7?GETtext/xml+votable180.050000true67.9460411-69.81930830.0055555555555555564/2068 5/8262-8263 8268-8269 8276 8278-8281 8284 8323-8324 8326 8329 8332 6/32953-32955 32958 33001 33045-33047 33080-33081 33084-33085 33108 33110-33111 33128-33129 33132-33133 33140 33144 33285-33287 33291 33300 33302 33310 33313 33315 33321 33324-33325 33327 37536 37538 375443.9193497546148093e-20 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/500/817?format=asciiInfrareddefaultJ/MNRAS/500/817/table7Final mid-IR catalogue for 2352 LMC and 2672 SMC fundamental mode Classical Cepheids in the Magellanic CloudsrecnoRecord number assigned by the VizieR team.
