We used the solar atlases of Delbouille et al (1973), from lambda 3000 Å to 10000 Å (step 2 mÅ)
and from Kurucz et al (1984) from lambda 4080 Å to 9950 Å (step 5 mÅ) at disk centre (mu = 1.0),
taken respectively at the Jungfraujoch station (Switzerland, a very high and dry site)
and Kitt Peak (USA). We restricted the wavelength range to lambda 3000 - 8800 Å for which we have
the line identification provided by the Moore table (Moore et al, 1966).
The equivalent Lande factors g* were also provided in the range lambda 3700 – 8800 Å,
as this is important to characterize the sensitivity to the Zeeman effect
(Stokes V and the circular polarization rate are proportional to g*).
The spectra are displayed by pages of 100 Å displaying bands of 10 Å.
Delbouille’s spectrum is shown in black, while Kurucz’s spectrum is plotted in green.
The blue numbers are equivalent Lande factors g*.
The line identification follows the convention of the Moore et al (1966) table
(slash for main contributors in case of a blend, dash for blends, parenthesis for masked lines,
p for predicted line, see page XVIII of their book for details).
The equivalent width w of lines (in fact 0.2*log(w), with w in mÅ)
is represented by the violet dashed vertical bars
(for instance, CaII K 3933.68 Å line has w = 20253 mÅ, which gives a bar length of 0.2*log(20253) = 0.86).
Limb spectra obtained by Stenflo (2014, 2015) with the FTS at Kitt Peak (USA)
and Gandorfer (2000, 2002, 2005) with ZIMPOL at IRSOL (Switzerland) are superimposed,
respectively for mu = 0.145 (blue dotted) and mu = 0.10 (red dotted).
All spectra (I/Ic) are normalized to the adjacent continuum Ic.
