Light curves were Fourier-decomposed and coefficients from WASP were transformed to the ASAS standard using 24 common stars. Coefficients were then compared with similar data from Galactic globular clusters, the Galactic bulge and the Large and Small Magellanic Clouds (LMC and SMC). Using Fourier coefficients, we also calculated physical parameters via standard equations from the literature. We confirmed the results of previous authors, including lower amplitudes and longer rise times for Blazhko stars. It was found that in the R_31_ versus R_21_ plot the location of a star depends mainly on its metallicity and that Blazhko stars prefer a different location from modulation-free stars. Field and globular cluster RR Lyrae variables have a different {phi}21 and {phi}31 from stars in the LMC, SMC and Galactic bulge. Although there are some weak indications that Blazhko stars could tend towards a slightly lower metallicity and shorter periods, no convincing proof was found. The most interesting highlight is the identification of a very recently proposed new group of metal-rich RR Lyrae type stars. These low-luminosity, metal-strong variables, comprising both Blazhko and regular stars, have shorter periods and about 180K higher temperature at constant (B-V)_0_ than the rest of the stars in the sample.2014MNRAS.445.1584Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/445/1584CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/113/1711 : RR Lyrae in NGC 6171 (Clement+ 1997)J/A+A/371/579 : Empirical relations for cluster RR Lyrae (Kovacs+, 2001)J/MNRAS/384/1444 : Vr light curves of NGC 5466 RR Lyrae (Arellano Ferro+, 2008)J/A+A/507/803 : VI photometry of new M53 variables (Dekany+, 2009)J/AJ/140/1766 : RR Lyrae in M62 (NGC6266) (Contreras+, 2010)J/MNRAS/416/2265 : Variable stars in NGC 5024 (M53) (Arellano Ferro+, 2011)J/MNRAS/419/2173 : Long-term photometry of M3 RR Lyrae (Jursik+, 2012)J/MNRAS/434/1220 : Vi light curves of NGC6333 variables (Arellano Ferro+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/445/1584https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/445/1584http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/445/1584https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/445/1584https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/445/1584http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/445/1584GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/445/1584/table2 (Fourier parameters of fundamental mode RR Lyrae variables located in globular clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/445/1584/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/445/1584/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/445/1584/table2?GETtext/xml+votable180.050000true198.2347518.12055560.005555555555555556Cone search capability for table J/MNRAS/445/1584/table3 (Parameters of sample stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/445/1584/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/445/1584/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/445/1584/table3?GETtext/xml+votable180.050000true353.775166741.10288890.0055555555555555566/110 1028 1294 2173 2238 2629 2703 2938 3176 3329 4219 4286 4479 4762 4828 4833 4900 4942 5182 5708 6567 6744 8612 8614 8864 9027 9095 9110 9138 9172 9438 9509 9635 9769 10169 10321 10336-10337 10362 10524 10541 10584 10638 10661 10792 10862 12463 12512 12632 12740 12743 12773 12781 13171 13343 13647 14373 14918 14939 15281 15886 16018 16553 16587 16602 16849 16867 17158 17328 18080 18177 18502 18640 19091 19104 19110 19169 19559 20020 20097 20303 20497 20681 20998 21111 21127 21146 21182 21209 21268 21533 21961 22111 22170 22338 22842 23271 23613 24724 24772 24866 25199 25485 25491 25611 25768 26079 26113 26131 26281 26288 26413 26435 26515 26894 26981 27356 27361 27474 27824 27975 27981 27998 28030 28143 28383 28426 28582 28674 28701 29009 29140 29225 29291 29307 29377 30019 30055 30769 30868 30923 31054 31390 31416-31417 31730 31743 31884 32052 32204 32257 32282 32354 32568 32636 32663 32903 32911 33432 33465 33467 33745 33994 33996 34229 34236 34240 34242-34243 34285 34423 34537 35423 35724 35768 35852 36040 36048 36225 36363 36605 36781 36912 37095 37302 37456 37544 37911 38087 38304 38350 38360 38393 38456 38511 38809 38947 39003 39152 40553 40651 40722 40767 40806 40882 40911 40988 40998 41011 41022 41081 41191 41219 41260 41285 41318 41345 41946 42260 42604 42658 42672 42841 42938 42965 43225 43227 43317 43391 43405 43419 43758 43764 43888 43977 43984 44425 44498 44559 44595 44838 44914 45062 45086 45152 45164 45324 45337 45539 45741 45767 45992 46069 46130 46327 46440 46520 46641 47043 47074 47140 47228 47327 47395 47467 47508 47527 47550 47618 47772 47776 47821 47856 48091 48113 48137 48165 48228 48290 48315 48661 48911 49102https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/445/1584?format=asciidefaultJ/MNRAS/445/1584/table2Fourier parameters of fundamental mode RR Lyrae variables located in globular clustersSimbadNameSimbad column added by the CDSmeta.idcharPer[0.3/0.9] Perioddtime.periodfloatrecnoRecord number assigned by the VizieR team.
