King 1968	R. C. King and G. T. Armstrong, J. Res. Natl. Bur. Stand. 72A, 113-131 (1968) Constant Pressure Flame Calorimetry With Fluorine II. The Heat of Formation of Oxygen Difluoride
note H2Ob	King 1968 reports Series I of 6 measurements as more reliable, and gives Delta_H_f_303.4(H2O ) = -285.67 kJ/mol and Delta_H_f_298.15(H2O ) = -285.84 kJ/mol with a std. dev +- 0.12 kJ/mol; for 6 measurements (5 degrees a freedom) and 95.45% confidence limits Student-t is 2.6487, producing an uncertainty of 0.32 kJ/mol (cf. to 0.33 given by King 1968)
