Observed Spitzer phase curve and the best fit sine curve to the Spitzer data (red dashed line with the one sigma uncertainty shaded in red) compared to four theoretical phase curves: the different three blue solid lines are phase curves for the 1D TBL model assuming an adiabatic, an isothermal and an temperature inversion case. We also generated a phase curve out of the pseudo-2D rock vapor model (solid pink line). The adiabatic, isothermal and rock vapor model all fit the observations well and the temperature inversion model provides the worst fit.
