Sensitivity curves for the flux calibration of all MEGADES observations. Panels a, b, and c show the sensitivity curves derived from all the standard stars observed with the LR-B, LR-V, and LR-R gratings, respectively. Cyan lines mark the spectral coverage after flux calibration in Angstroms for all fibres. Dashed brown lines indicate the spectral coverage after flux calibration in Angstroms, with a proper flux calibration.
