cds-question@unistra.frexoplanetsgravitational-lensinginfrared-photometryvisible-astronomyphotometryWe present the analyses of two microlensing events, OGLE-2018-BLG-0567 and OGLE-2018-BLG-0962. In both events, the short-lasting anomalies were densely and continuously covered by two high-cadence surveys. The light-curve modeling indicates that the anomalies are generated by source crossings over the planetary caustics induced by planetary companions to the hosts. The estimated planet/host separation (scaled to the angular Einstein radius {theta}E) and mass ratio are (s, qx10^3^)=(1.81{+/-}0.02, 1.24{+/-}0.07) and (s, qx10^3^)=(1.25{+/-}0.03, 2.38{+/-}0.08), respectively. From Bayesian analyses, we estimate the host and planet masses as (M_h_, M_p_)=(0.25_-0.13_^+0.27^, M{odot}, 0.32_-0.17_^+0.34^, M_J_) and (M_h_, M_p_=(0.54_-0.28_^+0.33^, M{odot}, 1.34_-0.70_^+0.82^, M_J_), respectively. These planetary systems are located at a distance of 7.06_-1.15_^+0.93^kpc for OGLE-2018-BLG-0567 and 6.50_-1.75_^+1.06^kpc for OGLE-2018-BLG-0962, suggesting that they are likely to be near the Galactic bulge. The two events prove the capability of current high-cadence surveys for finding planets through the planetary-caustic channel. We find that most published planetary-caustic planets are found in Hollywood events in which the source size strongly contributes to the anomaly cross-section relative to the size of the caustic.2021AJ....161..293Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/293CatalogResearchIsServedByTAP VizieR generic servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/AcA/50/421 : OGLE-II DIA BUL_SC1 field (Wozniak, 2000)J/A+A/428/587 : Cepheids BVRIJHK dereddened magnitudes (Kervella+, 2004)J/A+A/529/A102 : MOA-2007-BLG-387Lb light curve I band (Batista+, 2011)J/A+A/549/A147 : Abundances of microlensed bulge dwarf stars.
