Spectral cross-correlation templates

One of the redshift measurements is carried out by obtaing a cross-correlation redshift. The ID of the best-fitting template is stored in the header keyword BESTTEMP in the spSpec*.fits files. Here we provide the template spectra.

  • The templates have been changed slightly for DR2/DR3 (note they are now numbered from 0-32, instead of 1-33)
  • Templates are provided as fits files, in the same file format as spSpec*.fits files.
  • Get all templates: spectemplatesDR2.tar.gz (1.8 MB)
  • We also provide ps and gif plots of the templates.
