$\begin{figure} \par\includegraphics[width=11.5cm,clip]{0503fig1.eps}\end{figure}$ Figure 1: Logarithmically-scaled image of the quiet Sun obtained by integrating over the O VI $\lambda$ 103.193 nm line ( $3\times 10^5$ K) after subtracting the continuum. The minimum and the maximum of the image correspond to radiances around 14 and 4654 mW m^-2 sr^-1, respectively. Levels of the longitudinal magnetic flux of 10 G, 25 G and 40 G are shown with white (positive) and black (negative polarity) solid lines. The locations where non-Gaussian line profiles were found are marked with a black +.

Solid dark-grey and light-grey (red and light-blue in the electronic version) isocontours show the downward and upward mass fluxes, respectively. The contours are traced for levels of $\langle\overline{F^{\rm B,R}}+3~\sigma(F^{\rm B,R})\rangle=576$ (count^1/2 $\rm km~s^{-1}$ ). Levels of the longitudinal magnetic flux of (10, 25 and 40) G are shown with white (positive polarity) and black (negative polarity) solid lines. The locations where non-Gaussian line profiles were found are marked with a black +.

$\begin{figure} \par\includegraphics[width=11.5cm,clip]{0503fig4.eps}\end{figure}$ Figure 4: Detailed view of box A in Fig. 1 together with the line profiles at the indicated locations. a) Logarithmically-scaled radiance image. Isocontours of the negative polarity of the longitudinal magnetic flux at (-10, -25 and -40) G are shown with black solid lines (no positive flux above 10 G is present in the displayed area). Locations where non-Gaussian line profiles were found are marked with a black +. The dashed dark-grey (red) line indicates the projection (on the plane perpendicular to the LOS) of a semi-circular loop with a diameter of 13''. The loop is inclined by 18 $^{\circ }$ with respect to the LOS and the footpoint line rotated by 12.5 $^{\circ }$ clockwise. The black dots indicate the measured position of the observed loop. b) Line profile at a location on the northern leg of the loop. The bars indicate the data points. The thin solid lines show the three components used to fit the data while the resulting fitting profile is represented by the thick solid line. c) Line profile at the top of the loop. The dotted line shows the profile obtained averaging over the whole raster times 4.9. d) The same as for panel b) but for the southern leg of the loop.

$\begin{figure} \par\resizebox{8.5cm}{!}{\includegraphics[clip]{0503fig5.eps}}\end{figure}$ Figure 5: In the top panel the line radiance, L, along the loop (following the dotted line in Fig. 4a) is shown. The distance along the loop is reckoned from the southern extreme of the loop. In the bottom panel we show the speeds obtained by the moment analysis ( + symbols) together with the measurements obtained by the multi-Gaussian fitting (triangles). Negative values indicate blueshifts (upflows). For the sake of clarity, the two sets of measurements are slightly shifted with respect to each other in abscissa. A single Gaussian fit (square) and the first moment (asterisk) of the line profile at the loop top are also shown. The solid line indicate the LOS component for a 130 $\rm km~s^{-1}$ flow along the semi-circular geometrical loop whose projection on the plain perpendicular to the LOS is shown by the dark-grey (red) dashed line in Fig. 4a. The dotted lines are obtained for velocities of 90 and 170 $\rm km~s^{-1}$ .
