v1.8.4

v1.8.4

v1.7.0

• Improved the way the stellar limb is defined. LDTk now fits an LD model together with a smoothstep function to find the edge of the star. This approach should remove the need for manual edge definition completely.
• LDTk now resamples the original models to a linear sampling in mu since this makes LD coefficient estimation more straightforward.

v1.6.3

Bugfix release.

• Fixed a Windows compatibility issue.
• Fixed the PM version of power-2 model (the code was using log instead of log2 in coefficient transformation).

v1.6

Added ldtk.SVOFilter filter class that creates a filter using the Spanish Virtual Observatory (SVO) Filter Profile Service (FPS). The FPS contains over 10000 named filters, and creating a filter based on the FPS data is now as simple as giving the SVOFilter the SVO filter name.

v1.4.0

• Added automatic detection and re-download of corrupted fits files [contributed by T. Fatahi].

v1.3.1

• Changed to calculate most of the limb darkening modes with numba.
• Added support for using 5 nm low-resolution spectra (now a default). This should decrease cache size and download times significantly.

v1.0

Final cleanup and bugfixes

• Fixed a Python 3 compatibility issue in saving and loading LDPSets
• Added a set of basic transmission curves (sloan g, r, i, and z passbands approximated with Boxcar filters, and Kepler response function) that can be imported from ldtk.filters
• Upgraded the basic example notebook
• Changed to use setuptools in setup.py

v1.0-beta.5

• Python 3 compatibility fixes.

v1.0-beta.3

Bugfixes and a square root limb darkening model provided by Rainer Wichmann.

• Bugfix: The TEFF grid for TEFF > 7000 K was faulty, now fixed.
• Bugfix: The second term in the nonlinear limb darkening model had a wrong coefficient.
• Feature: Square root limb darkening model.

v1.0-beta.2

Python 2 & 3 compatibility.
