BAGLE - Bayesian Analysis of Gravitational Lensing Events

BAGLE is a python package used to model gravitational microlensing events both photometrically and astrometrically. Supported microlensing models include:

• PSPL: point-source, point-lens with and without parallax

• PSBL: point-source, binary-lens

  • static lens secondary

  • moving lens secondary with linear, accelerating, circular, or elliptical orbital motion.

• BSPL: binary-source, point lens

  • static source secondary

  • moving source secondary with linear, accelerating, circular or elliptical orbital motion.

• BSBL: binary-source, binary lens

  • static lens and source secondary

  • moving source or lens secondary with linear, accelerating, circular or elliptical orbital motion.

• FSPL: finite-source, point-lens

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