$\begin{figure} \par\includegraphics[width=7.5cm,clip]{4920fig1.eps} \end{figure}$ Figure 1: Vignetted MK4 negative images of the CME on 2004 August 18. The MK4 field of view is from 1.08 to 2.85 $R_{\odot }$ . Arrows indicate the CME heights measured along two dotted lines of the CME nose ( $\rm PA1 = 250^{\circ }$ ) and CME flank ( $\rm PA2 = 230^{\circ }$ ) near the helmet streamer, respectively.

Dotted white line in the upper panel indicates the frequency drift of the fundamental emission band of the burst. The dashed and solid lines in lower panel denote the GOES X-ray flux and total radio flux curve, respectively.

Coronal density was measured along the dotted lines at 9 position angles (a = 219 $^{\circ }$ , b = 225 $^{\circ }$ , c = 231 $^{\circ }$ (PA2), d = 237 $^{\circ }$ , e = 250 $^{\circ }$ (PA1), f = 270 $^{\circ }$ , g = 276 $^{\circ }$ , g' = 282 $^{\circ }$ , and h = 288 $^{\circ }$ , respectively).

$\begin{figure} \par\includegraphics[width=7cm,clip]{4920fig4.eps} \end{figure}$ Figure 4: Measured coronal density distributions along the position angles denoted in Fig. 3. The distributions at the northern flank of the CME at 276 $^{\circ }$ (g) and 282 $^{\circ }$ (g') are similar to each other. Dotted lines denoted as NK1 and NK2 represent the one- and two-fold Newkirk density models, respectively.

Each line denotes the coronal shock height estimated from the radio data and the measured coronal density distribution along the position angles. Dotted line represents the shock height estimated by assuming 20% density enhancement along PA2 during the period between 17:15 and 17:32 UT.

The error bars indicates the uncertainty ( $\pm$ 95 km $\rm {s}^{-1}$ ) of CME speed due to measurement errors (2-pixels) in MK 4 image.
