Considering the similar chemical property between Ho and these RE, it can be concluded that the enthalpies of formation of CoHo3 at 298 K should be around -10,000 J mol-1 , which is compatible with the presently assessed value, -10,539 J mol-1 .
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.
