Standard deviation (STD) of the simulated SC2 relative fluxes for different applied fiber offsets, either along or orthogonal to the dispersion direction. Black lines represent STDs with manual fiber tracking and no applied offsets, while green lines show STDs with applied offsets. The dotted lines indicate the respective wavelength average. An offset parallel to the dispersion direction shifts the characteristic “V-shape” toward positive wavelengths, and an antiparallel shift produces the opposite effect. Offsets orthogonal to the dispersion direction increase the overall STDs. The observed asymmetries between opposite offset directions arise from the asymmetry of the PSFs.
