$\begin{figure} \par\includegraphics[width=8.5cm,clip]{0490fig1.eps}\end{figure}$ Figure 1: Enlarged portion of the SUMER spectral atlas (Curdt et al. 2001) showing radiances of average QS (black), sunspot (red), and coronal hole (blue) regions. The network contrast (ratio bright network / cell interior in green), which is normally around 3, increases to values of 6 to 8 in TR lines, and the centroids of the contrast profiles are clearly redshifted.

$\begin{figure} \par\includegraphics[width=8cm,clip]{0490fig2.eps} \end{figure}$ Figure 2: Raster scan in the emission of N IV, Ne VIII and the continuum around 780 Å. In the continuum map brightness contours at 33% and 67% levels are overlaid. These have been used to define bright, faint and medium-bright pixels.

$\begin{figure} \par\includegraphics[width=12cm,clip]{0490fig3.eps}\end{figure}$ Figure 3: The shift of the network contrast relative to the position of the emission line as a function of formation temperature. Individual offsets have been determined for comparison with the profile of the bright pixels ( $\bigtriangleup$ ), the faint pixels ( $\circ$ ), and the average pixels ( $\Box$ ). The shift is scaled as Doppler flow. This is to make it comparable to earlier, direct measurements and should not be confused with a real flow.
