Notes. The lines are classified as “double-peaked” or disk-like (Dsk), “PCygni profiles” (PC). Those with complex, multicomponent wind absorption signatures are denoted as “PC+”. Potential blends and contamination by atmospheric features are denoted by “Bl” and “Atm”, respectively. Those that could not be classified are labeled as “INDEF”, and in some cases, a potential identification is given in the notes. The wavelengths provided are laboratory measurements (air), except for non-identified lines, for which we list the observed wavelengths. If the line is not seen, it is denoted as “N”, except if this part of the spectrum was not covered or if other features may have difficulted the identification, in which case we denote it as “-”. Lines denoted with vdA04 have been observed by van den Ancker et al. (2004) during the 1999 outburst. Lines denoted with WS have been identified using Wahlgren & Shore (S. Shore, priv. comm.), while the rest have been identified with the NIST database. Lines that are potentially pumped by other UV lines (Herczeg et al. 2005) are listed accordingly. For some of the close blends without clear peaks, the species cannot be easily identified. We note that the quiescence data had a lower spectral coverage, ending at ~6940 Å. The full table is available at the CDS.
