Comments on ``Improved limit on quantum-spacetime modifications of Lorentz symmetry from observations of gamma-ray blazars"
arXiv:gr-qc/0303001
Abstract
We address several criticisms by Amelino-Camelia of our recent analyses of two observational constraints on Lorentz violation at order E/M_{Planck}. In particular, we emphasize the role of effective field theory in our analysis of synchrotron radiation, and we strengthen the justification for the constraint coming from photon annihilation.
