First implementation of a script to list, add, remove, and plot the filters in the pcigale database. One or more filters can be added, removed, or plotted in one command.

Ensure that the .fnu @property returns a result even if the redshifting module has not been applied. By default in that case we assume a distance of 10 parsecs. Note that as the redshifting module is mandatory (it is needed to apply the IGM absorption, which has a small effect even at z=0 with this formula), it should not happen. Issue found by Yannick Roehlly.

Version 0.6.0

Implement a priodic SFH module in replacement of the sfhcomb_constant and sfhcomb_delayed modules. The new module handles rectangular, delayed, and exponential star-forming episodes.

Attempt to fix the fit in the presence of upper limit. For some reason the newton method sometimes does not converge. Patch by Denis Burgarella.

Attempt to fix the upper limit by revert a clearly wrong commit from 2014 which did the opposite of what was said in the comment …

Move the invocation of Matplotlib's Agg backend right after matplotlib's import. Even if it violates PEP8, it avoids some nasty warnings when runing pcigale-plots.

As the code is much faster now, let's update the number of computed models a bit less often as printing something on screen causes a context switch

We need to sort the sed.info before saving the data. The reason is that the dictionary orders the keys with a hash so it appears random. In addition the order also changes from one process to another (I suspect the hash also depends on a seed). Thanks to Yannick for pointing out this issue.

If there is the redshift information then there is necessarily the luminosity distance too. No need to test separately for the presence of each.

Normalise the SFH appropriately in the same if then else statement. Bonus is that is saves an array multiplication if a specific scaling factor is not given.

When computing the galaxy mass, convert from yr to Myr outside of the integral. That way we only multiply a scalar by 1e6 rather than a large array. Good for speed and memory bandwidth.

Simplify the construction of modules by remove the out_parameter_list dictionary. It was not used anywhere, was not always provided, and was not even up to date.

Switch back to ordered dictionaries for the input parameters after all. That way the list of parameters is kept into a logical order when building the configuration file. The impact on performance is negligible.
