Description:
This catalog contains wavelength information for 99 different atomic
species. The wavelengths for about 46,610 spectral lines of neutral
through quadruply ionized atoms are tabulated. The information is
presented in a general table of headers and references for each element
and for each element a table of relative
intensities, wavelengths ordered numerically, chemical elements, and
stages of ionization indicated for each line in the wavelength range
40 to 40,000 Angstroms. Listed in the 99 data files are lines that
appear in emission from the vacuum ultraviolet to the far infrared.
For most atoms these lines are chosen from much larger lists so as
to include the stronger observed lines in each spectral region. Below
2000 Angstroms the wavelengths are in vacuum; above 2000 Angstroms the
wavelengths are in air. Wavelengths given to three decimal places are
suitable for spectrograph calibration purpose such as Ne, Ar, Kr, Fe
in the air region and C, N, O, Si, and Cu in the vacuum region. The
intensity estimates are useful only as a rough indication of the
appearance of a spectrum. The literature references as they appear the
the the Handbook of Chemistry and Physics are given in a separate file.

Note on Int:
The spectral line intensities for each element are given as a guide
to the relative strengths of a line in the spectrum of that element.
From element to element and author to author different measures may
have been employed to derive these numbers.

Note on text:
In some cases the reference number is missing and the references are
ordered by the element and spectrum which then start the reference text
separating the identification and reference by a colon.

The original data files contained embedded headers and references.
That information for each elemental data file was extracted and
used to create the file refs.dat. In the file notes.dat other
information from the table header of each element including
the references to the table in the Handbook of Chemistry and Physics
are given. These references can be found in the hcp_refs.dat file
described above.

Remarks:
The brief description for the data was prepared by J. Lyu based on
documentation accompanying the catalog. Additional reformatting was
done by Paul Kuin (ADC). The original data and text were separated.
The data were reformatted and ion number was included. All elements
were combined in one data file. The header information was separated
to the file refs.dat and notes.dat. Additional notes were included as
required in the ReadMe documentation.
