Comparison of the extraction quality for two HARPS spectra of the B3IV star HD 60753 taken in the same night (S / N ~ 170). Top: extraction with FOX. Second panel: spectrum extracted with the HARPS DRS pipeline (not blaze corrected). Third panel: ratio of both exposures for FOX (red dots) and DRS (blue dots). Bottom: histogram of the ratio values. The black line is a Gaussian fit to the FOX histogram having a centre at 0.914 and a width of 0.00905.
