Abstract:
    We have built a line list in the near-infrared J and H bands
    (1.00--1.34, 1.49--1.80 {mu}m) by gathering a series of laboratory and
    computed line lists. Oscillator strengths and damping constants were
    computed or obtained by fitting the solar spectrum. The line list
    presented in this paper is, to our knowledge, the most complete one
    now available and supersedes previous lists.

    a =  0.05 dex
    b =  0.10 dex
    c =  0.15 dex
    d =  >0.15 dex
    f = indicates the gf-value of the line was fixed while the oscillator
        strengths of the neighboring lines were fitted; in these cases,
        the source of the gf fixed value is in most cases Kurucz (1995).
Note (2):
    The value is expressed in units of the Bohr radius squared
    (the Bohr radius is the constant 
         a_0_ = {epsilon}_0_ h^2^/({pi} m e^2^)
     from Permittivity, Planck, electron mass and charge constants )
Note (3):
    E =  Extrapolations in the calculation
    M =  Value computed using an enhancement factor larger than the
         classical van der Waals value
    A =  Value obtained from a fit to the solar spectrum
