Installation

$ git clone git@github.com:jpdeleon/chronos.git
$ cd chronos
$ pip install -e .

test

$ pytest tests/

Modules

  • target.py: star bookkeeping, e.g. position, catalog cross-matching, archival data look-up
  • star.py: physics-related calculations, e.g. extinction, spectral typing, isochrones, gyrochronology (inherits target)
  • planet.py: planet parameters calculations (inherits star)
  • tpf.py: targetpixel file manipulation
  • lightcurve.py: light curve analysis either using SPOC, QLP, or custom pipeline for short and long cadence (inherits tpf)
  • k2.py: tpf and light curve for K2; likely to be ingested/refactored to tpf.py & lightcurve.py
  • cluster.py: cluster catalog, cluster analysis + plotting
  • qlp.py, cdips.py, pathos.py, & diamante.py: api for QLP, CDIPS, PATHOS, and DIAmante pipelines
  • plot.py: custom plotting functionalities
  • utils.py: useful utilities

Dependencies

For next update

  • platon for calculating transmission spectrum
  • theJoker for two-body MCMC sampling
  • spock, dynamite, & resonance widths for orbit stability analysis
  • exoCMD for exoplanet color-magnitude diagrams
  • contaminante for pixel level modeling
  • allesfitter for light curve model fitting
  • SPISEA for stellar population analysis
  • sedfitter for SED fitting
  • maelstrom for pulsating binary analysis
  • stella & fleck for flare detection and modeling
  • eleanor & f3 for TESS FFI; See also DIAmante, Montalto+2020
  • envelope for planet's envelope fraction estimation using MESA simulations based on Milholland+19,20
  • evolstate for assigning stellar evolutionary state
  • barycorrpy for conversion to BJD_TDB
