Notes. Candidate star clusters detected with IRAF/DAOPHOT. Column 1 star cluster candidate ID; Cols. 2, 3 projected offset in arcseconds from the photometric nucleus (RA 20h37m14.123s, Dec 66°06′20.09′′); Cols. 4–15 absolute magnitude (m − M = 31.9), Mx, and error in magnitude, σx, in the F330W,F547M,F606W,F814W,F110W, and F160W band HST images. The candidates with a star in Col. 1 could not be fitted with an acceptable star cluster model in (see Sect. 6).

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.
