cds-question@unistra.frsolar-system-planetsWe analyse three years (1998-2000) of Optical Gravitational Lensing Experiment (OGLE) observations of microlensing events to place limits on the abundance of planets with a planet-to-star mass ratio q=10^-3^ at distances ~1-4AU from their host stars, i.e. 'cool Jupiters'. We fit a total of 145 events using a maximum-likelihood fit that adjusts six parameters. Each data point on the light curve allows us to exclude planets close to the two images of the source appearing on opposite sides of the Einstein ring of the lens star. We proceed to compute detection probability maps for each event, using {Delta}{chi}^2^ threshold values of 25, 60 and 100, and combine the results from all events to place global constraints. Our selection criteria returned five candidate events for a planet with mass ratio q=10^-3^.2003MNRAS.343.1131Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/343/1131CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toftp://sirius.astrouw.edu.pl/ogle : OGLE databaseJ/AcA/51/175 : OGLE-II DIA microlensing events (Wozniak+, 2001)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/343/1131https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/343/1131http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/343/1131https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/343/1131https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/343/1131http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/343/1131GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/343/1131/position (All microlensing candidates positions (from OGLE database))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/343/1131/position?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/343/1131/position?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/343/1131/position?GETtext/xml+votable180.050000true268.4181667-30.172250.0055555555555555565/7205 7216 6/28706 28716-28717 28725 28728 28730-28731 28734-28735 28768 28770 28778-28779 28819 28857 28868-28869 28880 28883 28887 28910 29065https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/343/1131?format=asciidefaultJ/MNRAS/343/1131/positionAll microlensing candidates positions (from OGLE database)recnoRecord number assigned by the VizieR team.
