Differential spectrum for 1ES 1959+650, combined with HEGRA points from Aharonian et al. (2003). Note that the lower HEGRA points are from a comparable (low) state of activity, (although there is no unique definition of "low state"); measurements during a flaring state are also shown (larger squares).
