Table 1:

Log of the VISIR observations of $\ell $ Car and RS Pup. MJD* is the modified Julian date of the start the exposures on the target minus 54 000, and $\phi $ the phase of the Cepheid. The Detector Integration Time (DIT) is given in milliseconds for one BURST image. $\theta $ is the seeing in the visible ( $\lambda=0.5~\mu$m) measured by the observatory DIMM sensor, in arcseconds, and AM is the airmass of the observation. The duration of each observation was 360 s on target.
