Notes. λuv(i1) and λuv(i2) correspond to the UV radiation wavelengths that depopulate the inter-combination level of a given element. All wavelengths are given in Å. φc are taken from Blumenthal et al. (1972). Hν/(h ν) are calculated with CMFGEN with our own abundances and mass-loss rate but with Teff determined in the UV/optical domain. The values are given in 108 photon cm-2 s-1 Hz-1. The oscillator strengths, f, are extracted from the AtomDB website.
