Since 2008, we have been observing Crab nebula/pulsar to assess the performance of the HAGAR telescopes as well as to detect pulsations. Technique used for analysis of HAGAR data will be discussed. Using 103 hours of data, we have detected Crab nebula at a significance level of 18 sigma at energies above 234 GeV. Also there is an indication of pulsations with period of 33 ms. Details of these results will be given. |
