.. _atlas_data_files: Atlases and calibration spectra files ===================================== These data files are needed for calculations involving source spectra. To install them locally, please download the relevant tarballs from `HLSP Reference Atlases `_. Then, move them to the appropriate location and extract them:: $ tar -xvf .tar $ rm .tar .. note:: Downloading and extracting the files might take a while as the tarballs combined are over 700 MB. Once installation is complete, you will see some sub-directories containing data as described below: +------------------------------------------+----------------+ |Description |Sub-directory | +==========================================+================+ |Interstellar extinction curves |extinction | +------------------------------------------+----------------+ |AGN templates |grid/agn | +------------------------------------------+----------------+ |Bruzual-Charlot galaxy spectra |grid/bc95 | +------------------------------------------+----------------+ |Buser-Kurucz stellar atlas |grid/bkmodels | +------------------------------------------+----------------+ |Bruzual-Persson-Gunn-Stryker stellar atlas|grid/bpgs | +------------------------------------------+----------------+ |Brown galaxy atlas |grid/brown | +------------------------------------------+----------------+ |Bruzual stellar atlas |grid/bz77 | +------------------------------------------+----------------+ |Galactic emission line objects |grid/galactic | +------------------------------------------+----------------+ |Gunn-Stryker atlas |grid/gunnstryker| +------------------------------------------+----------------+ |Jacobi-Hunter-Christian stellar atlas |grid/jacobi | +------------------------------------------+----------------+ |Kinney-Calzetti galaxy spectra |grid/kc96 | +------------------------------------------+----------------+ |Pickles stellar atlas |grid/pickles | +------------------------------------------+----------------+ |Castelli & Kurucz (2004) stellar atlas |grid/ck04models | +------------------------------------------+----------------+ |Kurucz (1993) stellar atlas |grid/k93models | +------------------------------------------+----------------+ |Phoenix stellar atlas |grid/phoenix | +------------------------------------------+----------------+ |HST calibration spectra |calspec | +------------------------------------------+----------------+
