Make sure the save_chi2 parameter is correctly acknowledged in pcigale-plots pdf. Otherwise this leads to a crash as it tries to build the PDF of parameters for which the corresponding chi2 files were not saved.

Use the Einstein summation convention to avoid the creation of temporary arrays when computing the likelihood-weighted means and standard deviations. This speeds up the evaluation of the physical properties and ultimately pdf_analysis can run more than 25% faster when evaluating a large number of physical properties with more than a million models.

Add a test to ensure that we are always in a situation where we can generate a valid pcigale.ini.spec file, otherwise raise en exception.

Handle the units for properties in log. Note that currently they cannot be saved properly in FITS files due to the format limit.

Switch the implementation to a suggestion made by Yannick. The speed is similar for small catalogues but it is substantially faster for large catalogues.

Handle the case where some bands do not have a best fit (e.g., in case the flux was not calculated because no object has a flux and the user did not add this band to the "band" parameter in pdf_analysis).

Ensure the figure is properly created and minimise the disturbance caused by the logo by placing it in the lower left corner.

Eliminate the unphysical wavy structure of the nebular continuum in the mid-infrared by pre-interpolating it on a refined wavelength grid in log-log space.

Improve the sanitation of input data so that upper limits of extensive properties are not eliminated from the quantities to be fitted when upper limits are activated
