Improved approach for fitting the error inflation of spectra in FitModel. Instead of fitting a constant, the free parameter is a scaling relative to the model fluxes (see Piette & Madhusudhan 2020). The use of the error inflation parameter has not changed but in this case typically requires a bound value between 0 and 1. Both run_multinest and run_mcmc have been updated.
The optional model parameter has been added to update_spectra since the error inflation requires calculating the model spectrum.
Bug fix with the use of fixed parameters in FitModel since the calibration and extinction parameters were not fixed.
The deredden parameter in add_object can also be a float (instead of dictionary), in which case the same dereddening is applied to all input data.
When fitting an atmosphere + disk, the disk_teff and disk_radius parameters are included in the luminosity calculation of plot_posterior.
A new grid of dust cross sections with a log-normal distribution has been calculated with a small improvement in the sampling of the distribution and in this case also ignoring grains smaller than 1 nm. The plot_size_distributions function has been updated accordingly. The new cross sections are downloaded and added to the Database with add_dust.
