Fitting Analysis using Differential Evolution Optimization (FADO)
Spectral population synthesis through genetic optimization under self-consistency boundary conditions
Latest stable distribution V.1.B: fadov1b.tar.gz.
Latest manual for distribution V.1.B: manual v1b.
FADO is a novel and innovative spectral population synthesis code having the currently unique capability of self-consistently fitting nebular and stellar emission. All distribution packages can be found at http://spectralsynthesis.org/fado-downloads.html. For a more detailed description see here.

Please use the latest distribution package (FADO V.1.B; released on 02/10/2018), which integrates several improvements and minor bug fixes (see revision history).

The binary of this distribution was compiled under OpenSuSE Leap 42.3 64bit LINUX with gcc version 4.8.5 (SUSE Linux) and should be compatible with most LINUX distributions. If you need other binary compilations, please access FADO downloads or send a message to Jean Michel Gomes.

The distribution package also contains two explanatory ascii files (ReadMe and Read_F), configuration files (FADO.config and PLOT.config), as well as the "Simple Stellar Population" (SSP) base library with the base file list Base.BC03.L. For testing purposes, the distribution package includes three characteristic de-redshifted spectra from SDSS-DR7 in ascii format, corresponding to a star-forming (spec1.txt), composite (spec2.txt) and LINER (spec3.txt) galaxy. Auxiliary files needed for execution of FADO (.HIfbound_em.ascii, .HeII_fbound.ascii, .HeIfboundem.ascii, grfont.dat and grfont.txt) are also included in the tarball. By decompressing the tarball the following six directories are created: input, output, plots, ReadMe, SSPs and tables.

Description
FADO V.1.B distribution package contains two different ascii files, ReadMe and Read_F, and one tarball archive fadov1b.tar.gz. fadov1b.tar.gz contains the binary (executable) compiled in both OpenSuSE Leap 42.3 64bit LINUX. The former is compatible with most LINUX distributions. It contains the configuration files for running FADO: FADO.config and PLOT.config, as well as the "Simple Stellar Population" (SSP) base library with the base file list Base.BC03.L, the FADO V.1.B short manual Read_F and this file (in the ReadMe directory) and, for testing purposes, three characteristic de-redshifted spectra from SDSS-DR7 in ascii format, corresponding to a star-forming (spec1.txt), composite (spec2.txt) and LINER (spec3.txt) galaxy. Auxiliary files needed for execution of FADO (.HIfbound_em.ascii, .HeII_fbound.ascii, .HeIfboundem.ascii, grfont.dat and grfont.txt) are also included in the tarball. By decompressing the tarball the following six directories are created: input, output, plots, ReadMe, SSPs and tables (see below for a brief explanation).
