d Kohstall et al. (1998).  
e Fawcett (1987).  
f Thomas & Neupert (1994).  
g Brosius et al. (1998). The SERTS-95 spectra were calibrated using atomic data from CHIANTI through insensitive line ratios, including several Fe XIII ratios, and so caution must be used when interpreting these values.  
h Brosius et al. (2000).  
i Malinovsky & Heroux (1973). Intensity errors on individual lines were not explicitly given, but relative intensities are good to 20% or better.
