If you use these spectra for your research, presentations, or papers, please
refer to this paper. 

(1) The cluster spectra:

The integrated-light spectra of the simulated clusters are provided in the
following 9 gzipped tar files, with file sizes listed in in the first column: 

 76MB    clusters_BaSeL_1e4.tar.gz
 15MB    clusters_BaSeL_1e5.tar.gz
534KB    clusters_BaSeL_1e6.tar.gz
 25MB    clusters_BaSeL_3e4.tar.gz
5.2MB    clusters_BaSeL_3e5.tar.gz
742MB    clusters_BTSettl_1e4.tar.gz
 69MB    clusters_BTSettl_1e5.tar.gz
247MB    clusters_BTSettl_3e4.tar.gz
 25MB    clusters_BTSettl_3e5.tar.gz

where "BaSeL" and "BTSettl" indicate the spectral library used to create the
integrated-light spectra (see paper for more details on that), and "1e4", "3e4",
etc., indicates the mass of the clusters in the tar file in question (in solar
masses).  Every cluster spectrum in these tar files is named as follows:

   clus_p<metallicity code>_<age code>.<simulation number>.spec.dat

where:

- metallicity code is the fractional part of Z
  (example: 'p008' means Z = 0.008). 
- age code is log(age/yr) in f5.2 format times hundred
  (example: '0980' means log(age/yr) = 9.80)

The spectra consist of ASCII files with two columns: Wavelength (in Angstroms)
and surface Flux density (in F_lambda units).

(2) The SSP spectra:

the integrated-light spectra of the simulated SSPs are provided in the following
two gzipped tar files, with file sizes listed in the first column:

1.9MB	SSP_BaSeL.tar.gz
 19MB	SSP_BTSettl.tar.gz

The naming and format of the SSP spectra are the same as those for the cluster
spectra described above. Note however that the cluster spectra used in this
paper were only created for Z = 0.008 while the SSP spectra were created for
Z = 0.002, 0.003, 0.005, 0.008, 0.012, 0.019, and 0.025.
