The TRDS Brown Atlas contains 129 spectral energy distributions for nearby galaxies, with wavelength coverage spanning from the ultraviolet to the mid-infrared.  Each of these files are part of the original  Brown Atlas (ref Brown et al. 2014), but with  a different format compliant with pysynphot and HST ETC.

The atlas consists of model spectra for a broad range of galaxy types, including ellipticals, spirals, merging galaxies, blue compact dwarfs, and luminous infrared galaxies. For more information about these models, please refer to Brown et al. 2014. The original files can be found in STScI HLSP pages

The files for the TRDS Brown Atlas can be found in here.

In the TRDS version, the FITS files are named based on the name of the object. For example for object NGC 0337 the file name is ngc_0337_spec.fits. These are FITS tables which contain two columns: the first one is the restframe wavelength in Angstroms and the second is the flux in FLAM units (\(ergs\ cm^{-2} s^{-1} A^{-1}\)).
