1. Source Region of Interest (RoI) intrinsic radius. Actual radii used are convolved with the analysis PSF. A zero value here refers to a point-source analysis.
2. Observation time (h) corrected to a 0.7 $^\circ$ off-axis angle using a standard cuts E>1 TeV response curve.
3. Statistical significance using Li & Ma (1983).
4. 99% C.L. flux upper limit $\times 10^{-13}$ ph cm^-2 s^-1.
§ Elliptical region ( $0.33^\circ \times 0.2^\circ$ with position angle 45 $^\circ$ ) as defined in Feretti & Neumann (2007).
