$\begin{figure} \par\includegraphics[width=8cm,clip]{1863fig1.eps}\end{figure}$ Figure 1: Beam pattern of the 30-m telescope within a radius of 14 $.\!\!^\circ$ 4 as derived from the aperture distribution. The gray scale is between -60 and -30 dB, contours are plotted from -50 to -20 dB in steps of 3 dB.

$\begin{figure} \par\includegraphics[width=8.8cm,clip]{1863fig6.eps}\end{figure}$ Figure 6: Mean brightness temperature at the cold sky position 1 (solid line). Included are the mean profiles for the total stray radiation which was subtracted (upper dashed line) and the stray radiation contribution originating from the far sidelobes (lower dashed line). Note the extended profile wings due to stray radiation.
