RR Lyrae stars RRAB, RRC, RRD, ARRD OGLE-IV (LMC) 60% >9%
RR Lyrae stars RRAB, RRC, RRD, ARRD OGLE-IV (SMC) 64% 15%
RR Lyrae stars RRAB, RRC, RRD, ARRD OGLE-IV (Bulge) 49% 44%

LPV MIRA_SR OGLE-IIIa (LMC+SMC) 40–50% <5%
LPV MIRA_SR Gaia DR2 withb ϖ∕σϖ > 10 – ~7%

Notes. For more details on the validation of the classification results, we refer to (Rimoldini et al., in prep.). (a) Estimates are restricted to sources with peak-to-peak amplitude >0.2 mag. (b) ϖ and σϖ refer to the DR2 parallax and associated error.

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.
