cds-question@unistra.frsurveyschemically-peculiar-starsnarrow-band-photometryThis paper presents the first public data release of the S-PLUS Ultra-Short Survey (USS), a photometric survey with short exposure times, cove ring approximately 9300deg^2^ of the Southern sky. The USS utilizes the Javalambr e 12-band magnitude system, including narrow and medium-band and broad-band filt ers targeting prominent stellar spectral features. The primary objective of the USS is to identify bright, extremely metal-poor (EMP; [Fe/H]<=-3) and ultra-metal-poor (UMP; [Fe/H]<=-4) stars for further analysis using medium- and high-resolution spectroscopy. This paper provides an overview of the survey observations, calibration method, data quality, and data products. Additionally, it presents the selection of EMP and UMP candidates. The data from the USS were reduced and calibrated using the same methods as presented in the S-PLUS DR2. An additional step was introduced, accounting for the offset between the observed magnitudes off the USS and the predicted magnitudes from the very low-resolution Gaia XP spectra. This first release contains data for 163 observed fields totaling ~324deg^2^ along the Celestial Equator. The magnitudes obtained from the USS are well-calibrated, showing a difference of ~15mmag compared to the predicted magnitudes by the GaiaXPy toolkit. By combining colors and magnitudes, 140 candidates for EMP or UMP have been identified for follow-up studies. The S-PLUS USS DR1 is an important milestone in the search for bright metal-poor stars, with magnitudes in the range 10<r<=14. The USS is an ongoing survey; in the near future, it will provide many more bright metal-poor candidate stars for spectroscopic follow-up.2024A&A...691A.138Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/691/A138CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttps://splus.cloud : S-PLUS Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/691/A138https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/691/A138http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/691/A138https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/691/A138https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/691/A138http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/691/A138GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/691/A138/tableb1 (Catalog of USS DR1 EMP and UMP candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/691/A138/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/691/A138/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/691/A138/tableb1?GETtext/xml+votable180.050000true1.65764711.39530810.0055555555555555565/7509-7510 6/12290 17741 17751 17762 17767 17856-17857 17998 18004-18005 18014 18017 18021 18027 18066 18069 18073 18078 18081 18087 18094 18098 18112 18176 18687 18766 18772 18778 18786 18788 18793 18796 18802 18830 18836 18838 18841 18850 18856-18857 18882 19023 19033 19036 19038 19045 19048 19052 19056 19089 19091 19098 19100 19108 19112 19114 19120-19121 19457 23142 23150 23190 23206 23216 30015 30023 30031-30033 30044 30050-30051 30054-30056 30058 30062 30072 30097 30099 30101-30103 30105 30108-30110 30146 49148-49150https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/691/A138?format=asciidefaultJ/A+A/691/A138/tableb1Catalog of USS DR1 EMP and UMP candidateszmagz (8936{AA}) band magnitude (AB) corrected for interstellar medium extinctionphot.mag;em.opt.IdoublerecnoRecord number assigned by the VizieR team.
