report
The enthalpy of formation of AuSb2 referred to fcc A1(Au) and rhombohedral A7(Sb) at 298 K is calculated to be -5409.55 J/mol, which agrees well with the experimental values measured by Hayer and Castanet [41] (-5400 ± 600 J/mol) as well as the assessed values by Liu et al. [20] (-4962 J/mol) and Kim et al. [32] (-5500 J/mol).

Uncertainty budget

Components kept separate, in the value's unit (literature SCHEMA.md, UNCERTAINTY_CALIBRATION.md): effective = max(sqrt(max(printed, reading, method)^2 + composition^2 + conversion^2), scatter). The method floor is the robust between-study scatter of the method class in ORCHID (calibrated) or a documented prior; printed values and printed uncertainties are unchanged.
