cds-question@unistra.frmilky-way-galaxyvariable-starsvisible-astronomysloan-photometryWe present the most extensive set to date of high-quality RR Lyrae light curve templates in the griz bands, based on time-series observations of the Dark Energy Camera Plane Survey (DECaPS) East field, located in the Galactic bulge at coordinates (RA, DEC)(J2000)=(18:03:34, -29:32:02), obtained with the Dark Energy Camera (DECam) on the 4-m Blanco telescope at the Cerro Tololo Inter-American Observatory (CTIO). Our templates, which cover both fundamental-mode (RRab) and first-overtone (RRc) pulsators, can be especially useful when there is insufficient data for accurately calculating the average magnitudes and colors, hence distances, as well as to inform multi-band light curve classifiers, as will be required in the case of the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST). In this paper, we describe in detail the procedures that were adopted in producing these templates, including a novel approach to account for the presence of outliers in photometry. Our final sample comprises 136 RRab and 144 RRc templates, all of which are publicly available. Lastly, in this paper we study the inferred Fourier parameters and other light curve descriptors, including rise time, skewness, and kurtosis, as well as their correlations with the pulsation mode, period, and effective wavelength.2025A&A...694A..72Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/694/A72CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/69/321 : OGLE RR Lyrae stars in Galactic bulge & disk (Soszynski+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/694/A72https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/694/A72http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/694/A72https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/694/A72https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/694/A72http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/694/A72GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/694/A72/tableb1 (Properties of 136 RRab and 144 RRc stars in the template data sample)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/694/A72/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/694/A72/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/694/A72/tableb1?GETtext/xml+votable180.050000true269.8222164-29.810410.0055555555555555565/7194 6/28735 28782 28821 28864-28865https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/694/A72?format=asciiOpticaldefaultJ/A+A/694/A72/tableb1Properties of 136 RRab and 144 RRc stars in the template data sampleRTRise timetime;arith.diffdoubleSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
