Description:
    In table 2 the log(gf) values for the 3d^8^+3d^7^ 4s-->3d^7^ 4p
    electric dipole (E1) transitions are given. This system is selected by
    cutting off energy values larger than 120,000cm^-1^ of both the even
    and the odd system in the final printing procedure; only log(gf)
    values larger than -3 are included. The first column of this table
    shows the wavelength obtained from the energy differences between the
    experimental level values. Wavelengths below 2000 Angstrom are given
    as vacuum wavelengths and above 2000 Angstrom as air wavelengths. The
    second column gives the log(gf) values followed by the J-value, energy
    value and the name of the lower (even) level. The first character of
    the level name designates the configuration number: for the even
    levels '1' refers to 3d^8^ and '2' to 3d^7^ 4s; for the odd levels '1'
    refers to 3d^7^ 4p. An '*' after the energy value indicates that the
    level is known, in which case the experimental level value is given.
    When unknown, the calculated energy value is given and used to
    approximate the wavelength.
    The A-values for the forbidden lines given in table 7 are restricted
    to the magnetic dipole (M1) and electric quadrupole (E2) transitions
    within the 3d^8^+3d^7^ 4s configurations, from levels with an energy
    of less than 50,000 cm^-1^ above the ground and with A-values larger
    than 10^-3^s^-1^. The level with the lower J-value is given first in
    the designation of the transition. The remaining columns are similar
    to the corresponding ones in table 2. The first character of the level
    name designates the configuration number: for the even levels '1'
    refers to 3d^8 and '2' to 3d^7 4s. An '*' after the energy value
    indicates that the level is known, in which case the experimental
    level value is given. When unknown, the calculated energy value is
    given and used to approximate the wavelength.
