\caption{\label{midi_log}Log of the MIDI observations of $\ell$~Car and RS~Pup. $\phi$~is the phase of the observation for the Cepheids, relative to the maximum light in~$V$ (see Sect.~\ref{intro} for $P$ and $T_0$~values), $B$~is the projected baseline length, PA~is the position angle of the projected baseline (counted East of North~$=$~$0^\circ$), and AM~is the airmass.}
