Fig. 11
The ratio between the apparent size of Sgr A* and the scattering size plotted as a function of wavelength for the major and minor axes. The scattering size is derived from the best fit of the scattering law in Bower et al. (2006), i.e., 
mas and (0.64
)
mas for the major and minor axes, respectively. Data are from An et al. (2005); Nord et al. (2004); Roy & Pramesh Rao (2003); Davies et al. (1976); Yusef-Zadeh et al. (1994); Bower et al. (2006, 2004); Jauncey et al. (1989); Lo et al. (1985, 1993); Alberdi et al. (1993); Marcaide et al. (1999); Krichbaum et al. (1993); Backer et al. (1993); Shen et al. (2005); Krichbaum et al. (1994); Rogers et al. (1994); Krichbaum et al. (1998b, 2006); Doeleman et al. (2001, 2008).
