Notes. From the left: ID of the clump (as used by Claeyssens et al. 2023), stellar mass, effective radius, observed distance from the centre of the galaxy. All values are taken from Claeyssens et al. (2023), except the distance that we computed from the source-plane image of Sparkler, as described in Sect. 2.
