Mastcam-Z multispectral database from the Perseverance rover's traverse through the Jezero crater Margin unit (sols 0-1269)

During its first 1269 sols of exploration, NASA's Mars-2020 Perseverance rover explored the igneous units of the Jezero crater floor, the sedimentary strata of the western Jezero fan front and top, the carbonate-bearing rocks of the crater's Margin unit, and sedimentary deposits within the Neretva Vallis channel. The rover's Mastcam-Z instrument, a pair of multispectral, stereoscopic, zoom-lens cameras, provides broadband red/green/blue (RGB), and narrowband visible to near-infrared color (VNIR, 440-1020 nm wavelength range). Here, we provide a database of Mastcam-Z spectra and multispectral image products from sols 0-1269. These include: the locations of the regions of interest (ROIs) from which the spectra were extracted; plots of spectra extracted from each observation; 'enhanced color images' derived by stretching narrowband images; and 'decorrelation stretch' (DCS) images that highlight the spectral diversity in left- and right-eye images. This dataset has been calibrated using Version 3 of Mastcam-Z's radiometric calibration pipeline, which includes a dust correction and significantly improves upon the calibration of the previous dataset for sols 0-707 (Rice et al., 2024, https://doi.org/10.25710/v4p4-s268).
