cds-question@unistra.frmultiple-starsexoplanetsvisible-astronomyWe use nearly 20yr of photometry obtained by the OGLE survey to measure the occurrence rate of wide-orbit (or ice giant) microlensing planets, i.e.,with separations from ~5a.u. to ~15a.u. and mass-ratios from 10^-4^ to 0.033. In a sample of 3112 events we find six previously known wideorbit planets and a new microlensing planet or brown dwarf OGLE-2017-BLG-0114Lb, for which close and wide orbits are possible and close orbit is preferred. We run extensive simulations of the planet detection efficiency, robustly taking into account the finite-source effects. We find that the extrapolation of the previously measured rate of microlensing planets significantly under-predicts the number of wide-orbit planets. On average, every microlensing star hosts 1.4^+0.9^_-0.6^ ice giant planets.2021AcA....71....1Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/71/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://ogle.astrouw.edu.pl/ogle/ogle4/planets : OGLE4 planets home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/71/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/71/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/71/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/71/1https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/71/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/71/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/71/1/fields (Information on fields studied)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/71/1/fields?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/71/1/fields?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/71/1/fields?GETtext/xml+votable180.050000true267.75-29.9966670.005555555555555556Cone search capability for table J/AcA/71/1/events (List of microlensing events analyzed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/71/1/events?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/71/1/events?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/71/1/events?GETtext/xml+votable180.050000true268.0807083-30.22052780.0055555555555555564/1795 1803 5/7177-7179 7192 7194-7195 7198 7200 7205 7209 7211 7216-7217 7220-7221 7226-7227 7230 7313 6/28702-28703 28705-28707 28747 28772 28774-28775 28786-28787 28796 28798 28804-28805 28815-28817 28819 28828-28829 28833 28835 28841-28843 28872-28873 28876-28877 28888-28889 28892-28893 28896 28898-28899 28902-28903 28914 28926 29058-29059 29064 29066 29184 29204-29205 29207 29249-29251 29256-29257 29260 29264-29266 29272 42366-42367 42452 424952.367228618189496e-19 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/71/1?format=asciiOpticaldefaultJ/AcA/71/1/fieldsInformation on fields studiedMedianDTMedian time difference between consecutive epochsdtime.epoch;stat.medianfloatrecnoRecord number assigned by the VizieR team.
