Ratios of the solar emergent intensity at the disc-centre calculated using ODF tables that were generated with different cutoff factors for the line pre-selection. Here cutoff factor refers to the opacity of a given line relative to the continuum opacity. If this ratio drops below the cutoff factor, this particular line is not included in the computation of the intensity spectrum. The default value of the cutoff factor is 10−3.
