After over 8 months of development, we are happy to release a brand new version of CIGALE. There are many bug fixes and improvements. In particular we would like to highlight the following:
- A new stochastic SFH module,
sfhstochastic_carvajal2025, has been added. It is based on a power spectral density technique. Details are provided in Carvajal+25. - The HST ACS/SBC filters have been added to the database.
- Given the significant differences between the HST WFC3 UVIS1 and UVIS2 filters, both versions are now available.
It is recommended to use a recent version of Python, it has been tested with version 3.12 and 3.13. However it should also work with older version (at least ≥3.9). As usual it is very strongly recommended to regenerate any pcigale.ini file with this new version.
