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.

Abstract:
    Radiative transition probabilities have been calculated for the
    magnetic dipole (M1) and electric quadrupole (E2) transitions
    connecting the 47 metastable energy levels in the 3d8, 3d7 4s and
    3d6 4s2 configurations in Co II. The most important configuration
    interaction (CI) and relativistic effects have been taken into account
    in the computations carried out with the help of the relativistic
    Hartree-Fock (HFR) method combined with a semi-empirical optimization
    of the radial parameters.
