Observations were made in three optical passbands (SDSS g', r', i'), and LCO's multi-site telescope network enabled the survey to achieve a typical cadence of ~10hrs in i' and ~15hrs in g' and r'. In addition, intervals of higher cadence (<1hr) data were obtained during monitoring of key microlensing events within the fields. This catalog includes the full timeseries photometry for all ~8 million stars, down to a limiting magnitude of i~18mag.2024PASP..136f4501Shttp://dc.g-vo.org/rome/q/ssa/infoSurveyResearchIsServedByGAVO Data Center ObscoreGAVO Data Center TAP serviceThe ROME/REA data is licensed under the `Creative Commons Attribution Share-Alike 4.0 License <http://creativecommons.org/licenses/by-sa/4.0/>`_ .. image:: /static/img/ccbysa.png :alt: [CC-BY-SA] This data release is a public product of the ROME/REA Key Project survey conducted on the robotic telescope network of the Las Cumbres Observatory (LCO).
