cds-question@unistra.frsurveysvariable-starsphotometryWe present the results of the first MOTESS-GNAT variable-star survey, a deep, wide-field variability survey conducted over 2yr with a total sky coverage of 300deg^2^. In this survey, we identified 26042 variable-star candidates with magnitudes R=13-19, including 5271 that are periodic at the 99% confidence level. We recovered 59 out of 68 members of the General Catalogue of Variable Stars (GCVS) that are in this brightness range. We discuss the implications for completeness and accuracy for both this survey and the GCVS; the implied completeness for distinctly classifiable variable stars in our survey is ~85%-90%. We also discuss some of the caveats of our survey results. We conclude that this instrument design is ideal for an inexpensive, longitudinally distributed telescope network that could be used to study faint or rare transient phenomena in a previously unexplored regime of parameter space.2007AJ....134.1488Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/1488CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://www.egnat.org : MG1 Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/1488https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/1488http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/1488https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/1488https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/1488http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/1488GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/1488/catalog (MG1 variable-star catalog (MG1-VSC))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/1488/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/1488/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/1488/catalog?GETtext/xml+votable180.050000true0.1895833.6763890.0055555555555555565/8 1028 2051 2052 3076 3080 4468 4532 4719 4723 4788 4803 5487 5492 5496 5535 5555 5556 5571 5572 5576 5727 5748 5816 5891 5892 5896 6515 6520 6559 6579 6600 6776 6835 7535 7539 7540 7544 7583 7599 7603 7604 7608 7619 7620 7624 7775 7791 7795 7796 7800 7855 7860 7876 7939 7940 7944 6/7 11 12 13 14 16 17 18 4102 4103 4107 4108 4109 4110 4128 4129 4130 4136 8199 8202 8203 8212 8224 8225 8226 12295 12298 12299 12300 12301 12302 12308 12328 17783 17787 17788 17789 17790 17847 17851 17852 17853 17854 17863 17865 17867 17868 17869 17870 17876 17880 17888 17889 17890 17892 18039 18043 18044 18045 18046 18102 18103 18107 18108 18110 18117 18119 18123 18124 18125 18126 18136 18144 18145 18146 18148 18181 18183 18187 18188 18189 18190 18192 18193 18194 18208 18209 18210 18805 18807 18811 18812 18813 18814 18870 18871 18875 18887 18889 18891 18896 18897 18898 18912 18913 18914 19063 19065 19066 19067 19068 19069 19070 19126 19127 19131 19132 19133 19134 19142 19143 19145 19147 19148 19149 19150 19160 19168 19169 19170 19172 19207 19211 19216 19217 19218 19220 19232 19233 19234 19236 19461 19463 19467 19468 19469 19470 19472 19473 19474 19488 19489 19490 21877 21879 21881 21883 21884 21885 21886 21942 21943 21946 21947 21957 21959 21963 21964 21965 21966 21988 22133 22134 22135 22137 22139 22197 22198 22199 22201 22202 22203 22204 22205 22206 22213 22214 22215 22217 22218 22219 22228 22232 22240 22241 22242 22244 22248 22279 22281 22282 22283 22292 22296 22308 22312 22902 22903 22905 22906 22907 22967 22969 22971 22972 22973 22974 22981 22982 22983 22986 22987 22988 22989 22990 22996 23008 23009 23010 23012 23157 23159 23161 23163 23164 23165 23166 23223 23227 23228 23229 23230 23239 23243 23244 23245 23246 23248 23249 23252 23256 23303 23307 23308 23309 23310 23312 23313 23314 23328 23329 23330 23559 23561 23563 23572 23576 23588 23592 25975 25979 25980 25981 25982 26039 26043 26044 26045 26046 26055 26059 26064 26065 26066 26088 26229 26231 26235 26295 26299 26300 26301 26302 26309 26311 26315 26320 26321 26322 26324 26336 26337 26338 26375 26379 26380 26381 26382 26384 26385 26386 26388 26999 27001 27003 27004 27005 27006 27063 27067 27068 27069 27070 27079 27083 27084 27085 27086 27088 27089 27090 27255 27259 27260 27261 27262 27319 27322 27323 27324 27325 27326 27334 27335 27339 27344 27345 27346 27360 27361 27362 27364 27398 27399 27403 27404 27405 27406 27408 27409 27410 27424 27425 27426 27655 27659 27660 27661 27662 27664 27665 27666 27668 27680 27681 27682 30069 30071 30073 30074 30075 30076 30077 30078 30133 30134 30135 30137 30138 30139 30150 30151 30153 30154 30155 30164 30168 30180 30184 30325 30326 30327 30329 30330 30331 30389 30390 30391 30393 30394 30395 30405 30407 30409 30410 30411 30436 30440 30469 30470 30471 30473 30474 30475 30484 30488 30500 30504 31093 31094 31095 31097 31098 31099 31157 31158 31159 31162 31163 31173 31175 31178 31179 31188 31192 31204 31350 31351 31355 31356 31357 31358 31413 31415 31417 31418 31419 31430 31431 31434 31435 31436 31437 31438 31444 31456 31457 31458 31460 31494 31495 31497 31498 31499 31500 31501 31502 31512 31520 31521 31522 31528 31749 31750 31751 31753 31754 31755 31764 31768 31780 31784https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/1488?format=asciiOpticaldefaultJ/AJ/134/1488/catalogMG1 variable-star catalog (MG1-VSC)recnoRecord number assigned by the VizieR team.
