Notes. Star: name of a RR Lyr star; Period: period of a RR Lyr star adopted from AAVSO database; ϖDR3: parallax from Gaia DR3 catalog corrected with Lindegren et al. (2021) corrections; RUWE: renormalized unit weight error from the Gaia DR3 catalog; GOF: goodness-of-fit from the Gaia DR3 catalog; E(B − V): reddening value applied from Schlafly & Finkbeiner (2011) reddening map corrected for the MW model by Drimmel & Spergel (2001); ⟨g⟩, ⟨r⟩, ⟨i⟩: intensity-averaged mean magnitude from Fourier series fitting for the Pan-STARRS gP1rP1iP1 filters, respectively; [Fe/H]: the adopted iron abundance; Source: source of iron abundance (1 – Crestani et al. 2021a; 2 – Crestani et al. 2021b).

(a)

Stars rejected based on the RUWE and GOF parallax quality parameters given by the Gaia DR3 catalog.

( * )The SED showed that the Sloan gri mean magnitudes are systematically fainter than the photomertic compilation from Monson et al. (2017).

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.

Initial download of the metrics may take a while.
