Abstract:
We have built a line list in the near-infrared J and H bands
(1.00-1.34, 1.49--1.80 µm) 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.

1- 7 A7 --- Ion Ion name
9- 16 F8.2 0.1nm Wave Wavelength (in Angstroms)
25- 29 F5.2 eV ExPot Excitation potential
33- 37 F5.2 --- log(gf) Log of the oscillator strength
40 A1 --- e_log(gf) [abcdf] Errors in the oscillator strength (1)
49- 56 E8.2 --- C6 Interaction constant for van der Waals
pressure broadening in a02 (2)
59 A1 --- n_C6 [AEM] Note on C6 (3)
65- 72 A8 --- n_Ion Note indicates either an isotope of
Nickel or an unlikely identification

Note (1):
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
a0 = ε0 h2/(π m e2)
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
