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 <filename>.tar
$ rm <filename>.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:
