Excercise on Forming an SED: 3C 454.3 during peak of late-2010 flare Goal: convert data into nu F_{nu} vs. nu table, with uncertainties, for plotting - For X-ray & gamma-ray regions, do this for different frequencies from start to end of frequency range # Multi-waveband data for 3C 454.3 at peak of late-2010 flare # JD = 2455519.5 +/- 0.5 # From Wehrle et al.
