Based on our nearly continuous, line-free spectra from 200-670 $\\mu$m, the calculated bolometric luminosities ($L_{\\rm bol}$) increase by 50% on average, and the bolometric temperatures ($T_{\\rm bol}$) decrease by 10% on average, in comparison with the measurements without Herschel. Fifteen protostars have the same Class using $T_{\\rm bol}$ and $L_{\\rm bol}$/$L_{\\rm submm}$.
