ISO LWS (43 to 197 micron) observations of Ceres, Pallas, Vesta, and Hygiea.
Apply a thermophysical model to the flux measurements to derive far-IR based diameter and albedo values.
Also find that the measured thermal rotational lightcurve of Vesta is well-matched to model predictions.
Find that the general agreement between the photometric observations and models is better than 5% for Ceres, Pallas, and Vesta and better than 30% for Hygiea.
