Abstract:
The homogenization of the stellar parameters is an important goal for
large observational spectroscopic surveys, but it is very difficult to
achieve it because of the diversity of the spectroscopic analysis
methods used within a survey, such as spectrum synthesis and the
equivalent width method. To solve this problem, constraints to the
spectroscopic analysis can be set, such as the use of a common
line-list.
We present a procedure for selecting the best spectral lines from a
given input line-list, which then allows us to derive accurate stellar
parameters with the equivalent width method.
Description:
Table 2 presents the atomic data for the final line list derived from
the procedure presented in the work.
