Table 1: Listed are data, image- and event-selection criteria. $n_{{\rm tel}}$and $n_{{\rm image}}$ indicating the number of active telescopes participating in the data taking and the number of images used for the event reconstruction respectively. $R_{{\rm meas.}}$ and $R_{{\rm CR}}$ are the average measured and expected trigger rate of the telescopes. $r_{{\rm core}}$ is the distance of the shower impact point to the position of the central telescope. The altitude angle above horizon is indicated as alt, whereas $\theta ^2$ is the squared angular distance of the shower direction to the source direction. The $\gamma $-hadron separating quantity mscw is further explained in the text. The image parameters distance and sizedescribe the position of the shower image centroid with respect to the center of the camera and the total amount of light (in photo electrons, p.e.) measured in the image.
