Notes. The celestial coordinates correspond to the epoch of the reference image, which is the HJD ~ 2 456 541.54 d. Epochs are (HJD – 2 450 000). ⟨ I ⟩ denotes mean I magnitude and Ai′ + z′ are the amplitudes found in our special i′ + z′ filter. The blend column describes whether the star is blended with (i) brighter star(s); (ii) star(s) of similar magnitude; or (iii) fainter/no star(s).

(a)

These stars have shorter periods than expected for stars of the SR class, but it is not clear how to otherwise classify them according to the GCVS schema given their position on the RGB.

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.
