Mars Raman spectra acquired with SuperCam on apatite SCCT (TAPAG) on different sols throughout the mission, normalized to the mean signal. The plots are color coded with sol number. (A) Normalized spectra (x axis shows wavenumber in cm⁻¹); (B) Close-view in the 900–1000 cm⁻¹ spectral range; baseline-corrected experimental data ( +) and fitted pseudo-Voigt profile (full lines). (C) Intensity of the \(\nu_{1}\) mode of apatite extracted from the normalized spectra (area of the fitted pseudo-Voigt profile) as a function of the sol of the observation. The error bars represent the uncertainty values of the parameters derived from the peak fitting procedure.
