Description:
Mean line profiles of the quiet Sun spectrum, recorded simultaneously
in Lα, Lβ, Ca II H and K, and Mg II h and k lines with the
OSO-8/LPSP spectrometer were derived for structures such as
supergranulation cell and network. We compare these observed profiles
with theoretical ones computed by Vernazza et al. (1981, VAL81) and
by Fontenla et al. (1993, FAL93). We also present our own theoretical
profiles : with our non-LTE radiative transfer codes, we compute the
line profiles corresponding to different atmospheric models, derived
from the reference VAL and FAL models. Finally, we propose two new
semi-empirical models, NET and CEL, which are in better agreement with
the network and cell line profiles observed by OSO-8.

Historical notes:
An inversion between NH and Ne columns was detected by the authors.
In the first line of table5, T=100000. instead of 1000000.
