cds-question@unistra.frgravitational-lensingexoplanetsinfrared-photometryvisible-astronomyphotometryWe inaugurate a program of "mass production" of microlensing planets discovered in 2021 KMTNet data, with the aim of laying the basis for future statistical studies. While we ultimately plan to quickly publish all 2021 planets meeting some minimal criteria, the current sample of four was chosen simply on the basis of having low initial estimates of the planet-host mass ratio, q. It is therefore notable that two members of this sample suffer from a degeneracy in the normalized source radius {rho} arises from different morphologies of closely spaced caustics. All four planets (KMT-2021-BLG-1391, KMT-2021-BLG-1253, KMT-2021-BLG-1372, KMT-2021-BLG-0748) have well-characterized mass ratios, q, and therefore are suitable for mass-ratio frequency studies. Both of the {rho} degeneracies can be resolved by future adaptive optics (AO) observations on 30m class telescopes. We provide general guidance for such AO observations for all events in anticipation of the prospect that they will revolutionize the field of microlensing planets.2022AJ....164..180Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/164/180CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/617/A135 : 20 years of photometric microlensing (Mustill+, 2018)J/AJ/159/98 : I-band LC of microlensing event KMT-2016-BLG-1836 (Yang+, 2020)J/AJ/159/262 : OGLE/KMTnet VI bands photometry OGLE2019-BLG-0551 (Mroz+, 2020)J/ApJ/903/L11 : OGLE and KMTNet light curve of OGLE-2016-BLG-1928 (Mroz+, 2020)J/A+A/649/A90 : KMT-2018-BLG-1025Lb I light curve (Han+, 2021)J/AJ/161/293 : LCs of OGLE-2018-BLG-0567 and OGLE-2018-BLG-0962 (Jung+, 2021)J/AJ/162/96 : Iband light curve of KMT-2016-BLG-2605 with KMTNet (Ryu+, 2021)J/AJ/164/75 : Light curve of microlensing MOA-2019-BLG-008L (Bachelet+, 2022)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/164/180https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/164/180http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/164/180https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/164/180https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/164/180http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/164/180GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/164/180/table1 (Event names, cadences, alerts, and locations)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/164/180/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/164/180/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/164/180/table1?GETtext/xml+votable180.050000true270.6835833-28.06050.0055555555555555566/28828 28851 28865 28882https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/164/180?format=asciiOpticalInfrareddefaultJ/AJ/164/180/table1Event names, cadences, alerts, and locationsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
