Notes. FWHM: full width at half maximum of intensity. l.c.: line centre at half maximum of intensity. p.s.: separation of emission peaks. p.m.: middle of emission peaks. abs1-4: radial velocities of absorption components.
The absorption components of the H I lines in the low-resolution spectrum on May 20, whose radial velocities are denoted by a dagger, are likely the blends of abs2 and abs3 in the high-resolution spectra. The observational errors in the radial velocities of broad emission and absorption components are about ±10 km s-1 for the high-resolution spectra (May 14, 15, and 16, and June 9 and 10), and ±30 km s-1 for the low-resolution spectra (May 20 and July 9). Values with larger errors are denoted by a colon.
