abstract: >-
  We present a python package ldtk that automates the calculation of custom
  stellar limb-darkening (LD) profiles and model-specific limb-darkening
  coefficients using the library of phoenix-generated specific intensity
  spectra by Husser et al. The aim of the package is to facilitate analyses
  requiring custom generated LD profiles, such as the studies of exoplanet
  transits -- especially transmission spectroscopy, where the transit modelling
  is carried out for custom narrow passbands -- eclipsing binaries,
  interferometry, and microlensing events. First, ldtk can be used to compute
  custom LD profiles with uncertainties propagated from the uncertainties in
  the stellar parameter estimates. Secondly, ldtk can be used to estimate the
  LD-model-specific coefficients with uncertainties for the most common LD
  models. Thirdly, ldtk can be directly integrated into the log posterior
  computation of any pre-existing modelling code with minimal modifications.
  The last approach can be used to constrain the LD model parameter space
  directly by the LD profile, allowing for the marginalization over the LD
  parameter space without the need to approximate the constraint from the LD
  profile using a prior.
