BAGLE - Bayesian Analysis of Gravitational Lensing Events

BAGLE allows modeling of gravitational microlensing events both photometrically and astrometrically. Supported microlensing models include:

  • PSPL: point-source, point-lens with parallax

  • PSBL: point-source, binary-lens

  • FSPL: finite-source, point-lens (currently testing further)

All models support fitting data with single or multi-band photometry only, astrometry only, or joint fitting of photometry and astrometry (recommended).
