648 PDS DSV 1 This table contains the percentage of total Fe in Fe-bearing phases from peak areas in Opportunity (MER-B) Moessbauer Spectra. In the field names, D=Doublet Moessbauer spectrum and S=Sextet Moessbauer spectrum, and the phase assignments are OL=Olivine, PX=Pyroxene, ILM=Ilmenite, CHR=Chromite, MT=Magnetite, NPOX=Nanophase Ferric Oxide, FE3SULFATE=Fe3+-bearing sulfate, JAR=Jarosite, HM=Hematite, PYR/MAR=Pyrite/Marcasite, GT=Goethite, TR=Troilite, and A-FE=Fe/Ni Metal Alloy. Values in fields named FE2D1 OL PCT, FE2D2 PX PCT, FE2D3 ILM PCT, etc., are the percentages of total Fe associated with the listed Fe-bearing phase. Values in fields named *_ERR are absolute errors. Thus, the first two table entries are equivalent to: OL = (39 +/- 2) %. An entry of 0 (zero) denotes that the doublet or sextet was not used in the least squares fitting procedure. Peak areas are f-factor corrected. 161 Carriage-Return Line-Feed Comma 42 0 "rover_id" 1 ASCII_String Rover identifier, A for MER-A (MER-2) or B for MER-B (MER-1).
