cds-question@unistra.frglobular-star-clustersvariable-starsinfrared-photometryvisible-astronomybroad-band-photometryWe characterize the absolute magnitudes and colors of RR Lyrae stars in the globular cluster M5 in the ugriz filter system of the Dark Energy Camera (DECam). We provide empirical period-luminosity (P-L) relationships in all five bands based on 47 RR Lyrae stars of the type ab and 14 stars of the type c. The P-L relationships were found to be better constrained for the fundamental-mode RR Lyrae stars in the riz passbands, with dispersions of 0.03, 0.02 and 0.02mag, respectively. The dispersion of the color at minimum light was found to be small, supporting the use of this parameter as a means to obtain accurate interstellar extinctions along the line of sight up to the distance of the RR Lyrae star. We found a trend of color at minimum light with a pulsational period that, if taken into account, brings the dispersion in color at minimum light to 0.016 mag for the (r-i), (i-z), and (r-z) colors. These calibrations will be very useful for using RR Lyrae stars from DECam observations as both standard candles for distance determinations and color standards for reddening measurements.2017AJ....154...85Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/85CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/202 : Globular Clusters in the Milky Way (Harris, 1997)J/ApJ/834/160 : ugriz colors of RR Lyrae stars in SDSS Stripe 82 (Ngeow+, 2017)J/other/ApSS/361.175 : M5 RR Lyr and HB VI light curves (Arellano Ferro+, 2016)J/ApJS/213/9 : Catalina Surveys periodic variable stars (Drake+, 2014)J/ApJ/765/154 : RR Lyrae stars in the Catalina Sky Survey (Drake+, 2013)J/ApJ/763/32 : Galactic halo RRab stars from CSS (Drake+, 2013)J/ApJ/632/266 : WFPC2 photometry of the globular cluster M5 (Layden+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/154/85https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/154/85http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/154/85https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/154/85https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/154/85http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/154/85GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/154/85/table3 (Periodic variable stars identified in the M5 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/85/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/85/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/85/table3?GETtext/xml+votable180.050000true228.8921251.82513890.005555555555555556Cone search capability for table J/AJ/154/85/table4 (Photometry within a radius of 17.7' from the center of M5)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/154/85/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/154/85/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/154/85/table4?GETtext/xml+votable180.050000true229.461472.299860.0055555555555555566/31410 31411 31416 31417 31419https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/154/85?format=asciiInfraredOpticaldefaultJ/AJ/154/85/table3Periodic variable stars identified in the M5 fieldLCLight Curvesmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
