Recovery fraction of GCs. Left panel: Fraction of added GCs that have been detected by the Euclid photometric pipeline as a function of the local residual surface brightness at the location of the GC. The four different symbols are denoting the different configurations of the simulations. Right panel: Fraction of detected GCs by the Euclid photometric pipeline as a function of the total input GC I_E magnitude. The Color codding is the same in both panels.
