Notes.
Periods are from Kaluzny et al. (2004), except for V80, V172, V173, V177, V180, V181, V183, and V411, which were derived by us.
Distance to the cluster center was calculated using the center of ω Cen as reported by SIMBAD: RA = 13:26:47.28, Dec = −47:28:46.1, both in J2000.
ID-53 in Weldrake et al. (2007).
ID-18 in Weldrake et al. (2007).
ID-49 in Weldrake et al. (2007).
V411 has the same coordinates and periods as first reported by Navarrete et al. (2013). Mean magnitudes differ from that paper because the values presented in this paper, but not in Navarrete et al. (2013), are intensity-averaged mean magnitudes.
ID-74 in Weldrake et al. (2007).
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.
