Abstract:
  This paper represents a collective effort to provide an extensive
  electronic database useful for the interpretation of the spectra and
  evolution of galaxies.  A broad variety of empirical and theoretical
  data are discussed here, and the data are made fully available in the
  AAS CD-ROM Series, Vol. 7.

  Several empirical stellar libraries are part of this database.  They
  cover the ultraviolet spectral range observed with IUE, optical data
  from different ground-based telescopes, and ground-based infrared
  data. Spectral type coverage depends on the wavelength, but is mostly
  complete for types O to M and luminosity classes V to I. A large
  metallicity range is covered as well.

  Theoretical libraries of selected spectral indices of cool stars and
  of stellar continuum fluxes in the temperature range 2000 K to
  50,000 K, as well as Wolf-Rayet energy distributions are presented.

  Several libraries of star clusters and early-type galaxies have been
  selected for this database. We discuss an extensive set of empirical
  spectral templates covering the wavelength region from 1200 -- 9800 A,
  as well as narrow-band line indices in a large number of passbands.
  Bench-mark spectra of nearby galaxies for model tests are included as
  well.

  We compiled numerous evolutionary models and isochrones for stars of
  all mass ranges of interest, wide metallicity range, and for all
  evolutionary phases, including the pre-main-sequence phase. The
  majority of the models have been computed by the Geneva and Padova
  groups.

  Evolutionary synthesis models computed by several independent groups
  are made available. They can be applied to old and young systems, and
  are optimized with respect to different aspects of input physics. The
  model predictions include stellar (colors, magnitudes, absorption
  features) and nebular (emission-line fluxes) properties.

  Finally, we present models of ionized gas to be used for the
  interpretation of active galactic nuclei and young star-forming
  galaxies

  The community is encouraged to make use of this electronic database
  and to perform a critical comparison between the individual datasets.

Description:
  The Database for Galaxy Evolution Modeling, as supplied by the authors
  consists of 2079 files comprising >268 Megabytes of data, mostly
  compressed with the 'gzip' compression program.  The file names do not
  conform with the ISO 9660 Interchange Level 1 standard used by the
  AAS CD-ROM Series, and the filenames themselves contain too much
  identifying information to make it feasible to rename the files to
  conform with the restrictive '8.3' DOS-style naming conventions of ISO
  9660.  To preserve the complete file names, all of the files have been
  placed into a single UNIX tar file called 'database.tar'.  A listing
  of all of the individual files inside the tar file, in UNIX 'ls -l'
  format, is contained in the file 'database.toc'.

  The Database can be extracted from the tar file onto the user's disk,
  but one should note the large disk space requirements.  In order to
  make it easier to extract selected portions of the database, a simple
  Perl 4 script, named 'extract.pl' has been provided that takes as its
  arguments an output directory to place the files into and a prefix
  that corresponds to a specific dataset within the tar file.  To
  execute the script, change directory to the CD-ROM directory that
  contains this document and the files 'extract.pl', 'database.toc', and
  'database.tar'.  Invoke the script with the output directory and
  dataset prefix as arguments, e.g.

        $ perl extract.pl $HOME/database DaSeBoJo

  For a listing of the major portions of the Database, see the table
  below, reproduced from the printed paper.  The reader is referred to
  the printed paper for complete descriptions of the Database.  The
  table lists the dataset, the section number from the printed paper
  that discusses that dataset, the number of files associated with the
  dataset, the format of the data ('ascii', 'fits', or 'tar'), and the
  identifier that can be used to extract that dataset with the
  'extract.pl' script.
