Telluric-corrected H-band spectrum of BD+44°493. Wavelengths are in vacuum, and no shift to the rest frame of BD+44°493 has been applied. A nominal atmospheric spectrum for Gemini North is overplotted in red. Metal absorption lines are indicated by vertical blue dashed lines, and their corresponding IDs are provided at the top. The strong absorption lines with the sharp cores at 1.588, 1.611, 1.641, 1.681, and 1.736 μm are the H Brackett lines in the spectrum of BD+44°493. The small emission bumps between 1.52 and 1.56 μm and the broad shallow red wings on the H lines are residuals from the telluric correction procedure and are due to the H Brackett series in the spectrum of the telluric standard.
