    • The term martian soil is used here to denote any loose, unconsolidated materials that can be distinguished from rocks, bedrock, or strongly cohesive sediments. No implication of the presence or absence of organic materials or living matter is intended.

    • The influence of the Mössbauer reference and main sources, mainly scattered high-energy radiation, was investigated during the development of the APXS. The introduced background was suppressed by a factor of 10 with 1-mm tantalum shields on the APXS and the Mössbauer instruments. Nevertheless, the resulting background was still 2.5 times that of the original.
