Notes. From left to right: HST instrument name, date of observation, filter of the observation, number of images, proposal ID, principal investigator and exposure time in seconds for each image. The asterisk (*) in the fifth column denotes the HST observations that were also used by Kumawat et al. (2024). Conversely, the observations used in their work but not used in our analysis are the WFC3/UVIS images from Proposal GO-12605, specifically in the F275W, F336W, and F438W filters. All WFC3/UVIS and ACS/HRC observations listed in the table were processed following the photometric reduction described in Sects. 2.1 and 2.2, and the resulting catalogues were subsequently used in the analysis. The only external catalogue used in this study is the one from Libralato et al. (2018, 2022) , constructed from the ACS/WFC observations.
