ΔH is the liquid-minus-solid value reported by the existing correction workflow. Each uMLIP row uses the sample set matched to that DFT method. Uncertainties are standard errors; — means unavailable.
ΔS is estimated as ΔHuMLIP/Tm,uMLIP. Its propagated uncertainty assumes these two quantities are independent. The current PBE/R2SCAN correction inherits this entropy estimate; it is not an independently calculated DFT entropy.

Values reported in SLUSCHI.out by the correction workflow. These are uMLIP potential-energy–temperature slopes for the PBE/R2SCAN sample sets, not full thermodynamic heat capacities or independent DFT heat capacities. The workflow may substitute the other phase's slope when one is unavailable. Uncertainties are not reported; — means unavailable.
