- ItemMillimagnitude photometry for OGLE transiting extrasolar planetary transits(2005) Minniti, D.; Fernández Contreras, José Miguel; Gieren, Wolfgang; Pietrzynski, Grzegorz; Ruíz, María Teresa; Udalski, Andrzej; Szeifert, Thomas; Ramírez, Sebastián; Zoccali, ManuelaVLT images in the V-band are used to make light curves of transits of candidate OGLE planets. The data for some of the targets are complemented with NTT K-band images. Using difference image photometry, we are able to achieve milli-mag errors in the individual datapoints. Here we discuss the observations, and data reductions. We also present the preliminary results for OGLE-TR-109, arguing that it is likely to be a new transiting planet....
