Event Assessment) Survey was a Key Project at Las Cumbres Observatory
(hereafter LCO) which continuously monitored 20 selected fields (3.76
sq.deg.) in the Galactic Bulge throughout their seasonal visibility
window over a three-year period, between March 2017 and March 2020.
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 (&lt;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.</description><source format="bibcode">2024PASP..136f4501S</source><referenceURL>http://dc.g-vo.org/rome/q/web/info</referenceURL><type>Survey</type><contentLevel>Research</contentLevel><relationship><relationshipType>IsServedBy</relationshipType><relatedResource ivo-id="ivo://org.gavo.dc/__system__/obscore/obscore">GAVO Data Center Obscore</relatedResource></relationship></content><rights rightsURI="https://spdx.org/licenses/CC-BY-SA-4.0.html">The ROME/REA data is licensed under the `Creative Commons Attribution Share-Alike 4.0 License &lt;http://creativecommons.org/licenses/by-sa/4.0/&gt;`_

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).  Individual images used in the data reduction are freely available
for download on the LCO archive (https://archive.lco.global/).

It is important to clarify that the light curves available through this
data release are not optimized photometric reductions of individual
objects.  Researchers intending to utilize this data set for publications
are kindly requested to acknowledge this source by citing the present paper
(Street et al 2024 :bibcode:`2024PASP..136f4501S`) along with the original
work by Tsapras et al 2019 :bibcode:`2019PASP..131l4401T`.

For research work that requires enhanced photometry for specific targets
within this catalog, we encourage reaching out to us directly.
Collaboration opportunities are sincerely welcomed, and we look forward to
supporting further inquiries and investigations.</rights><capability standardID="ivo://ivoa.net/std/SODA#sync-1.0"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="base">http://dc.g-vo.org/rome/q/sdl/dlget</accessURL><mirrorURL>https://dc.g-vo.org/rome/q/sdl/dlget</mirrorURL></interface></capability><capability standardID="ivo://ivoa.net/std/DataLink#links-1.1"><interface role="std" xsi:type="vs:ParamHTTP"><accessURL use="base">http://dc.g-vo.org/rome/q/sdl/dlmeta</accessURL><mirrorURL>https://dc.g-vo.org/rome/q/sdl/dlmeta</mirrorURL><queryType>GET</queryType><resultType>application/x-votable+xml;content=datalink</resultType><param std="true"><name>ID</name><description>The publisher DID of the dataset of interest</description><ucd>meta.id;meta.main</ucd><dataType arraysize="*" xsi:type="vs:SimpleDataType">char</dataType></param><param std="true"><name>responseformat</name><description>File format requested for output.</description><ucd>meta.code.mime</ucd><dataType arraysize="*" xsi:type="vs:SimpleDataType">char</dataType></param><param std="true"><name>maxrec</name><description>Maximum number of records returned.
