cds-question@unistra.frmagellanic-cloudsvariable-starsinfrared-photometryPeriod-luminosity relations (PLRs) of type II Cepheids (T2Cs) in the Small Magellanic Cloud (SMC) are derived based on OGLE-III, IRSF/SIRIUS and other data, and these are compared with results for the Large Magellanic Cloud (LMC) and Galactic globular clusters. Evidence is found for a change of the PLR slopes from system to system. Treating the longer period T2Cs (W Vir stars) separately gives an SMC-LMC modulus difference of 0.39+/-0.05mag without any metallicity corrections being applied. This agrees well with the difference in moduli based on different distance indicators, in particular the PLRs of classical Cepheids. The shorter period T2Cs (BL Her stars) give a smaller SMC-LMC difference suggesting that their absolute magnitudes might be affected either by metallicity or by age effects. It is shown that the frequency distribution of T2C periods also changes from system to system.2011MNRAS.413..223Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/413/223CatalogResearchIsServedByTAP VizieR generic servicerelated-toII/288 : IRSF Magellanic Clouds Point Source Catalog (Kato+ 2007)J/AcA/58/163 : VI light curves of LMC classical Cepheids (Soszynski+, 2008)J/AcA/60/17 : VI light curves of SMC classical Cepheids (Soszynski+, 2010)J/AcA/60/91 : VI light curves of SMC type II Cepheids (Soszynski+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/413/223https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/413/223http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/413/223https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/413/223https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/413/223http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/413/223GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap7.952274030004205e-20 1.7798557115773645e-19InfrareddefaultJ/MNRAS/413/223/table1The catalogue of OGLE-III T2Cs in the SMC with IRSF counterpartsTypeVariable typemeta.code;src.varcharrecnoRecord number assigned by the VizieR team.
