cds-question@unistra.frglobular-star-clustersvariable-starsinfrared-photometryThe period-metallicity-WISE W1- and W2-band luminosity relations are derived for RR Lyrae stars based on WISE epoch photometry for 360 and 275 stars in 15 and 9 Galactic globular clusters, respectively. Our final relations have the form <M_W1_>={gamma}_W1-(2.381+/-0.097)logP_F_+(0.096+/-0.021)[Fe/H] and <M_W2_>={gamma}_W2_-(2.269+/-0.127)logP_F_+(0.108+/-0.021)[Fe/H], where [Fe/H] values are on the scale of Carretta et al. (2009A&A...508..695C). We obtained two appreciably discrepant estimates for the zero-points {gamma}_W1_ and {gamma}_W2_ of both relations: one based on a statistical-parallax analysis - {gamma}_W1_=-0.829+/-0.093 and {gamma}_W2_=-0.776+/-0.093 and another, significantly brighter one, based on Hubble Space Telescope (HST) Fine Guidance Sensor (FGS) trigonometric parallaxes - {gamma}_W1,HST_=-1.150+/-0.077 and {gamma}_W2,HST_=-1.105+/-0.077. The period-metallicity-luminosity relations in the two bands yield highly consistent distance moduli for the calibrator clusters and the distance moduli computed using the W1- and W2-band relations with the HST zero-points agree well with those computed by Sollima, Cacciari & Valenti based on their derived period-metallicity-K-band luminosity relation whose zero-point is tied to the HST trigonometric parallax of RR Lyrae itself ({Delta}DM0 =0.04 and 0.06, respectively, with a scatter of only 0.06).2014MNRAS.439.3765Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/439/3765CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/328 : AllWISE Data Release (Cutri+ 2013)V/97 : Updated 3rd Cat Variable Stars in Globular Clusters (Clement+ 1997)J/PASP/121/1378 : Positions of variable stars in globular clustershttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/439/3765https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/439/3765http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/439/3765https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/439/3765https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/439/3765http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/439/3765GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/439/3765/table1 (The data for RR Lyraes in the calibrator GCs)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/439/3765/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/439/3765/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/439/3765/table1?GETtext/xml+votable180.050000true154.4165667-46.44389170.0055555555555555566/9666 10321 10336-10338 12405 12425 27975 27981 27984 27986 27992 31416-31417 38465-38468 41304 42955 43225 43227 43230 43249 47825 47828 479713.830199579824256e-20 6.513807192489934e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/439/3765?format=asciiInfrareddefaultJ/MNRAS/439/3765/table1The data for RR Lyraes in the calibrator GCsrecnoRecord number assigned by the VizieR team.
