What is recorded here?
Bond and colleagues analyzed an event independently observed by the OGLE and MOA surveys. Both light curves showed a roughly seven-day deviation from a single-lens profile, including a caustic feature. Their binary-lens fit favored an extreme mass ratio of about 0.0039, supporting a planetary companion to the foreground lens. A later Hubble analysis reported excess blended light and a color-dependent centroid shift consistent with a main-sequence lens star, and combined those data with the microlensing fit to estimate the system properties.

Scientific scope
The planet is inferred from a lensing light curve, not directly imaged. The original mass ratio was more directly constrained than individual masses; the original host and companion mass estimates assumed a main-sequence primary and Galactic model, while alternative primary types and another planetary fit were considered. The later Hubble source and lens were not separately resolved: both excess flux and centroid evidence were relatively weak, and a source companion and extinction were included in the Bayesian analysis. The later authors reported an error in the previous lens-mass range; neither estimate is a direct dynamical mass. Some mathematical symbols and signs in the later v1 render incompletely, so precise numerical transcription requires independent version or font verification. The reports have different author lists; the full list of individual contributors is not shown.
