a) TPM analysis of all available thermal measurements. The reduced χ²-values are shown for two different spin vector orientations: equator-on (solid lines) and pole-on (dashed lines), each time for two different values for the rotation period. The 3-σ confidence level for the TPM fit to the observations is also shown; b) the best TPM solution is shown together with the observed fluxes; c) the same model, but now shown in the observation/TPM picture.
