Comparison of WICKED and the code by Perna et al. (2023) at correcting for wiggles. The left panel shows the performance of both codes at recovering the wiggles model (shown in black in the bottom panel) added to the spectrum of the A-star J1757132 (solid black line). In the right panel we compare the performance of both codes at recovering the wiggles when the shape of the continuum is different from the integrated spectrum. We modified the spectrum by adding dust extinction with a value of A_V = 20, using the Infrared-Optical relation by Cardelli et al. (1989). As shown WICKED is better at recovering the wiggle then the code by Perna et al. (2023), specially when the integrated spectrum is not a perfect model for the spectrum.
