High-resolution (0.008~cm-1) Fourier transform spectra of water vapor were measured in the 1.5 and 1.9~µm regions. Some 733 absorption lines were fit by nonlinear least squares, yielding line positions, intensities and self-broadening coefficients. Comparison to the HITRAN database shows that these new fitted parameters are, in many cases, improvements over those currently in HITRAN. Water vapor in the 1.9~µm region has not been updated since HITRAN 86, nor have the strongest lines in the 1.5~µm region. (Lines of medium strength in the 1.5~µm region were updated more recently, using the measurements of Toth .)
