Fig. 2

Top three panels: completeness functions from artificial star tests for the three different filters for NGC 3808B. Each subpanel shows the completeness as a function of distance from the PRG’s center in three annuli specified in the legend. Bottom panel: overall completeness at all radii for NGC 4650 A is shown, where the individual radial incompleteness is nearly identical to the top three panels (see Sect. 2.4). Dash-dotted horizontal lines indicate the 50% and 90% completeness levels. Solid curves show the power-law fits to the completeness results.
