Properties of the sources detected by EXOD. Test observations with the detection parameters listed in Table 2: empty markers. All observations with the parameters in Table 3: filled markers. Left: number of detected sources as a function of DL. Right: fraction of sources confirmed to be variable through the χ² and KS tests among the detected ones as a function of DL. The colors correspond to different TW: light green for TW = 3 s, light blue for TW = 10 s, medium blue for TW = 30 s and dark blue for TW = 100 s. The shapes represent the box size: triangles for b = 3 × 3 pixels and circles for b = 5 × 5 pixels.
