Fig. 1
Emissivity ratio curves relative to the full-Sun spectrum of Malinovsky & Heroux (1973), and the atomic data from GT98, AK05 and SZ10. Iob indicates the observed irradiances (10-3 erg cm-2 s-1). The indices of the lower and upper levels as in Table 1 and the present experimental wavelengths (Table 2) are also shown.
