Data The HST Advanced Camera for Surveys (ACS) images use the Wide Field Channel (WFC) in the F555W and F814W filters, have an angular resolution of 0.1″ and reach exposure times of 2,406 s and 2,439 s, respectively. The observations were carried out in September 2022 under HST programme ID 16890 (ref. 52) and the resulting images of
