SuperCam calibration targets on board the perseverance rover: Fabrication and quantitative characterization

Acknowledgements The authors would like to acknowledge Jeremy Guignard for his advice concerning the sample preparation for the EMPA analyses, as well as the Centre Castaing in Toulouse and the IsTep facility (UMR 7193) and ALIPP6 at Sorbonne University in Paris for their help, support and reactivity for the quantitative characterization of the samples. Authors would also like to acknowledge the SAP facility in Aude, France, for their help and professionalism concerning the machining of most of the targets, as well as Geoffroy Chevallier for the sintering of most targets in Toulouse, Florian Mercier (MATEIS, Lyon) for the SPS and Guillaume Servin (SCERAM, Lyon) for the machining done in Lyon. Also, the authors would like to thank the Ecole des Mines , for the natural diopside that comes from their collection. The authors would like to thank as well The Carlsberg Foundation (grantCF16-0981) for supporting the purchase of parts, tools and processes for producing targets 1 through 5. Authors would like to acknowledge Adrian Brown for his very useful inputs concerning orbital observations at Jezero crater. Authors would also like to thank all the engineering and technical team of SuperCam. The SuperCam project is supported in the US by NASA's Mars Exploration Program, and in France by CNES. Last, authors would also like to acknowledge the support of the International Space Science Institute (ISSI).
