Add the computation of the integrated stellar luminosity.

CHANGELOG.md

@@ -7,6 +7,7 @@
 - Bands with negative fluxes are now considered valid and are fitted as any other band. (Médéric Boquien)
 - Allow the models to be computed by blocks in `savefluxes`. This can be useful when computing a very large grid and/or to split the results file into various smaller files as large files can be difficult to handle. The number of blocks is set with the `blocks` parameters in the pcigale.ini. (Médéric Boquien)
 - Allow the observations to be analysed by blocks of models in `pdf\_analysis`. This is useful when computing a very large grid of models that would not fit in memory. The number of blocks is set with the `blocks` parameters in the pcigale.ini. (Médéric Boquien)
+- The integrated stellar luminosity is now provided as `stellar.lum`. (Médéric Boquien)
 
 ### Changed
 - Make the timestamp more readable when moving the out/ directory. (Médéric Boquien)
