%\caption{\textbf{The expected relative change in the CMB temperature in the different frequency bins of Planck. The satellite can constrain deviations from a blackbody spectrum by comparison with a highly calibrated blackbody emitter in the low-frequency instrument and by coupling different frequency bins to the same cooling source. This should allow Planck to determine the absolute temperature at frequencies below 70 GHz with a precision of about $4\times10^{-7}$. See section \ref{obs} for more details.}}
