Version 2022.0

After a year and a half of hard work we are happy to release a new version of CIGALE. It comes with many new features and bug fixes in addition to various optimizations, making it better and faster all around. In particular we would like to highlight the following:

  • All the developments made in X-CIGALE have been merged into CIGALE, which will directly include any future development regarding X-rays. Check out Yang et al. (2020, 2022) for a detailed description.
  • New state-of-the-art nebular models made with CLOUDY have replaced the older version (Villa-Vélez et al. 2021). In addition, the respective metallicities of the stars and the gas are now decoupled and it is possible to choose from different electron densities.
  • The command line interface is now colorful and animated, including progress bars and summary tables with pcigale genconf/check/run so you have all the information you need at a glance.
  • The database format has changed, dropping sqlite. This should be transparent for most users but this means that some limitations have been removed and writing a module to store information into the database is much easier.
  • How data are stored in memory has been optimized leading to speedups of up to 50% when building the grid of models.
  • A different optimization has led to an improvement of up to 25% in the analysis speed.

Note that the minimum version requirement of Python has been bumped to 3.8 and the rich package has been added as a new dependency. As usual it is very strongly recommended to regenerate any pcigale.ini file with this new version.
