This standardized document follows the rules of the Standard Description for Astronomical Catalogues. For those having to work on this catalogue using FORTRAN programs, this ReadMe file can be transformed into a f77-compliant program which reads the files making up this catalogue, in two versions: either a f77 program loading whole files into arrays, or a f77-program reading each data file line by line.

Description:
In table 2 the log(gf) values for the 3d8+3d7 4s-->3d7 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 3d8 and '2' to 3d7 4s; for the odd levels '1'
refers to 3d7 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 3d8+3d7 4s configurations, from levels with an energy
of less than 50,000 cm-1 above the ground and with A-values larger
than 10-3s-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.
