New constraints on the formation of the helium lines
We analyse observations of the helium lines obtained with CDS onboard SOHO. The He I 584.3 Angstrom/O III intensity ratio shows a lower limit and an upper limit that decrease with increasing 0 in intensity. At low O III intensities this ratio increases significantly. An upper limit arises naturally...
