  • a All center shift values (CS) are quoted relative to α-iron. Errors are typically ±0.01, although they may be larger for components B and C due to their partially resolved nature and low intensities. QS, quadrupole splitting; W, line width at half height.

  • b Relative total iron content derived from the Mössbauer data.

  • c Determined by chemical analysis and quoted as a percentage of dry weight.
