Epoch 14, 2008 December 07. (a) Core spectrum. (b) Core-shift vectors of all frequency pairs, including intermediate frequencies denoted by Xl (7.9 GHz), Xh (8.9 GHz), Kl (21.8 GHz) and Kh (24 GHz). (c) Power-law fit (red curve) using all bands. (d) Core-shift vectors without the U band, (e) Power-law fit (red curve) using all bands except the U band. This approach leads to a better fit.
