- It is now possible to fit any physical property indicated by the code (e.g. equivalent width, dust luminosity, etc.). For this the physical property needs to be given in the input file and the properties to be fitted must be given in the properties filed in pcigale.ini. (Héctor Salas & Médéric Boquien)
- It is now possible to fit emission lines. For this the line has to be indicated in the same way as any other band both in the input flux file (in units of W/m²) and in the list of bands in `pcigale.ini`. Lines are prefixed with `line.` followed by the name of the line, for instance `line.H-alpha` for Hɑ. The following lines are supported at the moment: `Ly-alpha`, `CII-133.5`, `SiIV-139.7`, `CIV-154.9`, `HeII-164.0`, `OIII-166.5`, `CIII-190.9`, `CII-232.6`, `MgII-279.8`, `OII-372.7`, `H-10`, `H-9`, `NeIII-386.9``HeI-388.9`, `H-epsilon`, `SII-407.0`, `H-delta`, `H-gamma`, `H-beta`, `OIII-495.9`, `OIII-500.7`, `OI-630.0`, `NII-654.8`, `H-alpha`, `NII-658.4`, `SII-671.6`, `SII-673.1`. (Médéric Boquien)
- Two new dust attenuation modules have been added: `dustatt\_modified\_CF00` and `dustatt\_modified\_starburst`. The former implements a modified 2-component Charlot & Fall (2000) model whereas the latter implements a modified starburst law with the continuum attenuated with a Calzetti (2000) curve and the lines extincted with a Milky Way or a Magellanic Cloud law. The previous models `dustatt\_powerlaw`, `dustatt\_2powerlaws`, and `dustatt\_calzleit` are still available but are deprecated. (Médéric Boquien & David Corre)
- In addition to the physical properties, the fluxes are now also estimated through a Bayesian analysis. (Médéric Boquien)
### Changed
- The `sfhdelayed` module has been extended to optionally include an exponential burst to model the latest episode of star formation. (Médéric Boquien & Barbara Lo Faro)
