The figure shows the targets studied by SHERLOC on Mars' crater floor. It includes: a) A HiRISE image of the area with the rover's path and targets labeled. b) A chart showing fluorescence detections from survey scans of each target. c) WATSON images of natural and abraded targets, with SHERLOC scan footprints marked.

Figure 2 Summary: a: This shows the distribution of fluorescence peak wavelengths (λmax) for different targets on Mars. It compares natural and abraded targets in the Máaz and Séítah regions. b: The mean fluorescence spectra for each target group show typical band positions and feature similarities across targets, with data filtered to remove boundary artifacts below 270 nm.

Figure 3: Part a and b show colorized images of the Bellegarde and Quartier targets on Mars. Green rings indicate where a specific fluorescence doublet (around 303 and 325 nm) was detected during scans. Part c shows the median fluorescence spectra from these green-ringed areas. It compares the intensity of fluorescence at around 303 nm for two locations, Bellegarde (red) and Quartier (black). Part d presents Raman spectra from Quartier, showing high-intensity fluorescence points. It helps identify specific minerals by showing peaks at certain values, like around 1,649 cm⁻¹, indicating mineral presence.
