Correction of the brightest spaxel in the F170LP cube of the A-star J1757132 using the CLEAN_CENTRAL_SPAXEL step in WICKED. The top panel shows the original spectrum (red) with prominent wiggles. The aperture (3-pixel radius) and annular integrated (3- to 5-pixel annular radius) spectra are displayed in gray and yellow, respectively, with the best-fit model shown in blue. Subtracting this smooth model from the single spaxel data produces the wiggle spectrum (middle panel, gray). WICKED identifies peaks and valleys in the wiggle spectrum (green crosses) and fits a wiggle model (red), which is subtracted to produce the final wiggle-free spectrum (bottom panel, red), pink vertical lines mark masked regions, while the yellow area highlights the gap between the NRS1 and NRS2 detectors.
