Selected open clusters for validating APs
Listed in IVOA Registry (Virtual Observatory)
Reliable stellar atmospheric parameters are essential for probing stellar structure and evolution, and for stellar population studies.
Description
However, various deviations appear in comparisons with different ground-based spectroscopic surveys. We aim to select high-quality open cluster members and employ the atmospheric parameters provided by the theoretical isochrones of open clusters as a benchmark to assess the quality of stellar atmospheric parameters from Gaia DR3 and other ground-based spectroscopic surveys, such as LAMOST DR11, APOGEE DR17, GALAH DR4.
We selected 130 open clusters with well-defined main sequences within 500pc of the solar neighborhood as a benchmark sample to estimate the reference atmospheric parameters of the members from the best-fit isochrones of those clusters. By comparing the atmospheric parameters provided by different spectroscopic surveys to the theoretical parameters, the atmospheric parameter deviation and the corresponding dispersions exhibit different variations.

The atmospheric parameter deviations of F, G, and K-type stars are smaller than those of B, A, and M-type stars for most surveys. For most samples, the dispersion of T_eff_ decreases as temperature decreases, whereas the dispersion of logg shows an opposite trend.
