$\begin{figure} \par\includegraphics[width=5.8cm,clip]{6244fig1.eps}\end{figure}$ Figure 1: Fisher Discriminant (FD) distributions; a) for $\theta ^2$ < 0.05 degree² (point-source assumption), b) $\theta ^2$ < 0.25 degree² (0.5-degree diffuse), and c) the Monte-Carlo gamma-ray events. The black data point with error bars were obtained from the ON source runs. The green histograms were made by the OFF source runs. Note that the vertical normalization of each histogram was a result of the fitting procedure described in the text. The blue points were the background-subtracted data and the red histograms are best fitted signals.

$\begin{figure} \par\includegraphics[width=5.8cm,clip]{6244fig2.eps} \end{figure}$ Figure 2: $\theta ^2$ (degree²) distributions for |FD| < 1, a) and b). The black points with error bars are obtained by the ON source runs. The green histogram in a) was obtained by the OFF source runs which was normalized by the observation time. The green histogram in b) was by "wobble background'' from ON source runs normalized by the inverse of the number of "wobble points'' (=1/6). The red points were obtained by the background subtractions. Zero level is shown by the dotted line. The black points in c) is obtained by the fitting procedure described in the text. The red histogram in c) is 2 $\sigma$ upper limit for the point source assumption. The blue in c) is the expected yield assuming the CANGAROO-II flux.

$\begin{figure} \par\includegraphics[width=7cm,clip]{6244fig3.eps}\end{figure}$ Figure 3: Excess count map. The rainbow map is the excess count. The black contour is DSS2 (second version of Digital Sky Survey) data. The dotted circle is 0.5 degree radius. The point spread function is shown in left-below corner (the dashed line).

$\begin{figure} \par\includegraphics[width=5.85cm,clip]{6244fig4.eps}\end{figure}$ Figure 4: Integral fluxes. The points with error bars are the CANGAROO-II's ones (see text for the detail). The black curve is 99% upper limit (UL) by HESS for point source assumption. The green is that for 0.5 degree diffuse source. The red is 2 $\sigma$ UL for this observation for point source assumption and the blue for 0.5 degree diffuse.
