Table 6: Flux and spectral measurements of the Crab, divided up by data set as outlined in Table 1, for a power law fit with an exponential cutoff. Results for the various selection cuts described in Table 2 are also compared. The results for a power-law fit (PL) and for a broken power-law fit (BPL) are also given. The spectral fit estimated using the ring background model is given (ring), as is that estimated without the optical efficiency correction (uncorr.). Only statistical results are shown in the table. Similar measurements from other experiments are given for comparison, the Whipple results is taken from Mohanty et al. (1998), the CAT results from Masterson et al. (1999) and the HEGRA results from Aharonian et al. (2004b).
