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:
    A comprehensive set of accurate atomic data is required for analyses
    of astrophysical and solar spectra. CHIANTI provides a database of
    atomic energy levels, wavelengths, radiative data and electron
    excitation data for ions which are abundant in cosmic plasmas. The
    most recent electron excitation data have been assessed and stored
    following the method of Burgess & Tully (1992A&A...254..436B). The
    current version is essentially complete for specifying the emission
    spectrum at wavelengths greater than 50Å. A list of observed lines
    in the spectral region between 50 and 1100Å has been compiled and
    compared with the lines predicted by the CHIANTI database. The CHIANTI
    database reproduces the vast majority of lines observed at these
    wavelengths. CHIANTI includes IDL (Interactive Data Language) routines
    to calculate optically thin synthetic spectra for equilibrium
    conditions. IDL routines to calculate theoretical line intensities
    required for electron density or temperature diagnostics and emission
    measure studies are also included. The CHIANTI atomic database and
    supporting IDL routines are available by anonymous FTP.

Note (1): The observed wavelength is given as 0. if there is not report of an
           observed line at the wavelength of a reasonably intense line
           predicted by CHIANTI
Note (2): The intensity is given a 0. if the line is identified but is not
           included in the CHIANTI database.
