First and third row: major (first row) and minor (third row) axis sizes of the jet model as a function of observing wavelength for both thermal and κ electrons together with measured intrinsic sizes of Sgr A* reported by Bower et al. (2006) and Doeleman et al. (2008). Dotted lines are for three values of q. Second and fourth rows: relative difference between κ-jet and thermal-jet size for the major (second row) and minor axes (fourth row).
