^a The ionization potential in eV of the next lower ion. ^b Given in km s^-1. ^c Peak intensity in units of 10^-14 erg cm^-2 s^-1 Å^-1. The indices on the measured intensities stand for: ^A As measured in LWR05596, ^B LWP28122, ^C LWP25995, ^D SWP02326, ^E SWP55055, ^F SWP47715, ^G SWP02334. tcp = Two component profile as the spectral line has a narrow emission component superimposed on the broad white dwarf wind profile.
