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

• PSBL: point-source, binary-lens

  • static lens secondary

• BSPL: binary-source, point lens

  • static source secondary

  • source secondary moving with linear motion

  • source secondary moving with accelerating motion

  • source secondary moving on circular orbit

  • source secondary moving on elliptical orbit

• BSBL: binary-source, binary lens

  • static lens and source secondary

• FSPL: finite-source, point-lens

• Parallax for all of the above

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