Description:
Results of the search for gamma radiation above 15 TeV, using the
AIROBICC air shower detector, from a set of 196 candidate point
sources taken from different catalogs. For each object, the equatorial
coordinates are provided, together with the number of signal events
registered by the detector, the estimated background, the statistical
significance of the excess (or defect) of events, the average energy
threshold of the observation (in TeV), and the flux upper limit (at
90% confidence level) of gamma rays above this threshold.
