Notes: HeII6680 line are indicated by a “*”. In the last column: “SiIII” means that the SiIII 4552-5568-4575 lines are detected. “CIII/OII/NII” means that the lines CIII 4650 / OII 4640-4650 blend and NII 4631 are well detected (but not resolved). In the last column the spectral types are from Simbad (the references are: Hardorp et al. 1964; Georgelin et al. 1973; Uranova 1977, citealtNesterov95; Kobulnicky et al. 2010; Comerón & Pasquali 2012, Maíz Apellániz et al. 2016; Berlanas et al. 2018, 2020; Chick et al. 2020; Dinçel et al. 2024) or (in bold) from GAIA DR3 astrophysical parameters Table (see https://gea.esac.esa.int/archive/documentation/GDR3/).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
