| Why this differs from similar rows: Table 1 experimental column cites a single source, Fiquet et al. [2000] (K0=253, K'=3.9); sibling row instead reports a value derived by combining several data sets. | ||||||||||||||||

| Why this differs from similar rows: Text-stated combined value (K0=256, K'=3.9) derived from several data sets [Mao 1991; Wang 1994; Funamori 1996; Fiquet 2000], distinct from the single-source Table 1 value. | ||||||||||||||||
