cds-question@unistra.frsurveysvariable-starsphotometryWith the 1m Schmidt telescope of the Llano del Hato Observatory and the QUEST CCD camera, 380{deg}^2^ of the sky have been surveyed for RR Lyrae variables in a band 23 wide in declination (centered at DE=-1{deg}) and covering right ascensions from 4.1h to 6.1h and from 8.0h to 17.0h. The bright limit (due to CCD saturation) and the faint limit are V~13.5 and ~19.7, respectively, which correspond to ~4kpc and ~60kpc from the Sun. We present a catalog of the positions, amplitudes, mean magnitudes, periods, and light curves of the 498 RR Lyrae variables that have been identified in this region of the sky. The majority of these stars (86%) are new discoveries. The completeness of the survey has been estimated from simulations that model the periods and light curves of real RR Lyrae variables and take into account the pattern of epochs of observation. While the completeness of the survey varies with apparent magnitude and with position, almost everywhere in the surveyed region it is quite high (>80%) for the type ab RR Lyrae variables and between 30% and 90% for the low-amplitude type c variables.2004AJ....127.1158Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/127/1158CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/127/1158https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/127/1158http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/127/1158https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/127/1158https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/127/1158http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/127/1158GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/127/1158/table2 (RR Lyrae Stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/127/1158/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/127/1158/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/127/1158/table2?GETtext/xml+votable180.050000true61.6837083-0.37483330.0055555555555555565/5460 6479 6483-6484 6488 6499 6504 6543 6547 6563 6824 7823 7827 7843-7844 7848 6/21495 21497 21500-21501 21503 21815 21817 21819-21820 21823 21831 21834 21839 21844 21846 21848-21850 21856 21865 21893 21904-21905 21907-21908 21910 21913 22184 22773 22775 22783 22874 22880-22881 22883-22884 22889-22890 22919 22923 22926 22928 22931 22934 22938 22945 22947-22948 22950 23119 23125 25590-25591 25596 25598-25599 25847 25849 25851-25854 25913-25915 25925 25929 25931 25940 25945-25946 25956-25958 25960-25962 25990-25991 25993 25995 26001-26002 26004-26006 26008 26020 26022 26024-26026 26165-26167 26171 26182-26183 26186-26187 26193-26196 26200-26201 26208-26209 26211-26212 26216-26217 26247 26251 26258-26259 26261 26264-26266 26272-26274 26276 26278 26280-26282 26875 26877 26879 26935 26937 26941 26951 26955-26958 26964-26966 26970 26977-26979 26982 26984-26986 27013 27015 27019 27021-27022 27026 27028 27030 27032 27041-27042 27048 27191 27195 27197 27206-27207 27212-27213 27216-27217 27220 27224-27225 27232 27235 27270 27278-27281 27284 27286 27288-27290 27301 27306 30965 30967 30971 30973-30975 31115 31136 31138-31139 31144 31146 31287 31302-31303 31312-31313 31316 31318 31320-31322 31328-31329 31331-31332 31336 31338 31367 31380-31381 31384-31385 31396-31398 31403 40950 40956-40957 40959 45045-45047 45049 45051-45054https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/127/1158?format=asciidefaultJ/AJ/127/1158/table2RR Lyrae StarsTypeType of RR Lyrae starmeta.code;src.varcharrecnoRecord number assigned by the VizieR team.
