Abstract We investigate the physical mechanisms of high-energy gamma-ray emission from the TeV-emitting misaligned active galactic nucleus IC 310. 8 yr of data from the Fermi Large Area Telescope (Fermi-LAT) between 100 MeV and 500 GeV are reduced and analysed to study the temporal and spectral characteristics of IC 310. Point spread function-partitioned instrument response functions are used to improve the resolvability of IC 310 from nearby NGC 1275. Systematic effects due to this choice of instrument response functions and the proximity of NGC 1275 are investigated. We find strong spectral variability and detect the hard flaring state of IC 310 along with a previously undiscovered soft state in quiescent periods, and the first detection with Fermi-LAT below 1 GeV. This represents a shift in peak Compton energy of more than 5 orders of magnitude. Possible interpretations are discussed, but we lack the instantaneous sensitivity with Fermi to probe the underlying physics.

Beer’S Law

The distinction between the terms photometric accuracy, photometric linearity, and adherence to Beer's Law is discussed. To describe the last, a new term “analytical linearity” is suggested. Some instrument response functions which exhibit acceptable analytical linearity are shown, nevertheless, to be photometrically inaccurate. Methods of measuring true photometric accuracy, the search for absolute photometric standards, and the ultimate limitations of such standards are reviewed.
