Nebular Emission-Line Measurements

  • Using the method of Sarzi et al.(2006), called GANDALF (Gas AND Absorption Line Fitting) code, we match the stellar continuum and the nebular emission.
  • We include two reddening components in our models : the first which affects the entire spectrum, representing dust diffusion everywhere throughout the target galaxy ; and the second, which affects only the nebular emission and can account for dust more localized around the emission-line regions.
  • A complete list of the emission lines that were fit, including their intrinsic relative strengths, is given in the following table.

DOWNLOAD (306 MB) : observed fluxes, A/N

(in case of failure for the internal reddening correction, ‘observed fluxes’ are highly recommended to use.)

 

Emission fluxes, errors and so on.
